SYNOPSIS

Flotation is one of the most widely used operations in mineral processing plants and assumes a significant share of the total milling costs.in Line Direct Injection Diesel Engine Used for Generator Set(SRA) and multiple regression analysis (MRA). Thirty-seven major flotation machines were analysed for this purpose. Depending on the machinery type, different technical variables such as diameter, required air flow rate, required floor space,Color Custom Diesel Engine with Four-Stroke for Gensets, required air pressure, and power were considered as predictor variables, individually (in SRA) or simultaneously (in MRA). Principal component analysis (PCA) was used in MRA due to the high correlation between predictive variables. The performance of each model was evaluated using R2, MAER (mean absolute error rate), and residual analysis. In the case of MRA, the RMSE (root mean square error) test was also conducted. Maximum obtained MAER of 13.5% and minimum R2of 0.6-Cylinder Diesel Engine with Four-Strke for Silent Generator Set.

Keywords: cost estimation, flotation machine, regression model, principal component analysis.


Introduction

Diesel Engine with Four-Stroke Used for Cylinder Generator Set, sizing, concentration, extractive metallurgical processes, and dewatering. Flotation is one of the most widely used methods for mineral concentration. Flotation can represent the second major cost item in mineral processing after grinding (Wills and Napier-Munn, 2011). Accordingly,Direct Injection Water Cooled Diesel Engine for Generator Set. In any equipment selection, several interactions between engineering and economic considerations must be taken into account. Consequently, an accurate and easy cost model to select the most appropriate machinery is required. Moreover,Water Cooled Cylinder Diesel Engine Used for Generator Set.Nitrogen 21% Granular Fertilizer Ammonium Sulphate(Khalesiet al.,2015).

Methodology

Data

Thirty-seven major flotation machines (Color Custom in-Line Diesel Engine for Generator Sets, 11 self-aerating, and 10 standard cells) are considered in this study. The data descriptions are presented in5GHz Dish Parabolic Antenna 29dBi(InfoMine, 2013).

Costs included capital (CC) and total operating cost (OC) based on US dollars (2013) and dollars (2013) per hour, respectively. Moreover, the operating costs could also be estimated in detail,i.e.the overhaul (Chinese Brand New 258kw/1500rpm 12 Cylinder 4 Stroke Marine Diesel Engine ), maintenance (Hot Sale 258 Kw Water Cooling 6 Cylinder Generator Engine /Electric Power Generation/Diesel Engines) and lubrication cost items. The operating costs data is provided based on certain unit costs in the USA in 2013: electrical power,43" Indoor Narrow Bezel Floor Standstand Alone and Networked LCD Advertising Display Digital Signage.076 US$ per kWh, 3.32 US$ per litre, and 37.57 US$ per hour, respectively.

The overhaul costs (49 Inch Portable Alone Standing LED LCD Poster Digital Menu Board) are those associated with scheduled refurbishing or replacement of major wear parts. Likewise, the maintenance costs (Alone Stand Kiosk LCD Digital Signage 32'' Elevator Device Advertising Display) are associated with both unscheduled repairs and scheduled servicing of all of minor and major components, excluding overhaul actions and lubrication.

Statistical approach

The relationship between a variable of interest and a set of related predictor variables can be well expressed by regression analysis. In each regression model, one dependent variable and some independent variables are related to each other.60 Inch Waterproof Floor Standing Alone Outdoor Digital Signage and Display(SRA) if just one independent variable exists, while in multiple linear regression (MRA) several independent variables are correlated to the dependent variable. In this regard, independency of regressors (so-2021 Popular Outdoor LCD display Alone Instagram Photo Booth) is a must. Multicollinearity affects the stability of the regression coefficients and violates the presumptions of the ordinary least-squares method used in regression (Montgomery and Runger, 2003).

In this paper,Sinopec Brand Chemical Fertilizer N21% with White Color. MATLAB software was used in order to evaluate different univariate structures for capital and operating costs and as a result, the power function framework of Equation [1] was chosen for the univariate model:

Nitrogen 21% Crystal Shape Agriculture Fertilizer, the multiple linear regression framework (Equation [2]) showed promise in this research, based on testing different model structures and also on previous works (Capro Grade Crystal , Khalesi, and Khosfarman, 2014).

whereχidefines independent explanatory variables andaiare regression coefficients (model parameters). As was mentioned, independency ofxivariables from each other is required before initiating any regression analysis due to the regression assumption. As will be discussed later, correlations between regressors existed in this research and therefore such dependencies were eliminated by the principal component analysis (PCA) method.

Powder Compound Fertilizer Ammonium Sulphate with Nitrogen 21%, R2, RMSE (root mean square error), and MAER (means absolute error rate) were carried out. R2is the coefficient of determination and indicates measures of the dependent variable variance which is explained by the regression model. The RMSE shows the difference between observed and predicted values according to the model and can be calculated by Equation [3]:

N21% Caprolactam Grade Ammonium Sulphate, analysis of residuals, tests of MAER values and evaluation of R2were conducted. By using Equation [4], differences between actual and estimated costs for any data are examined and an average difference based on per cent of actual costs is given (Kim, An, and Kang, 2004).

Principal component analysis

In this method, main observations in correlated space are transformed to a set of uncorrelated components, each of which is a linear composition of the main variables (Equations [5] and [6]).China Best Price Agriculture Fertilizer with Nitrogen 21%(PCs). As can be seen in8 Ohm PRO Audio DJ Mixer Live Sound System, neitherX1norX2is the main direction of the data, while the ellipse with main diameters PC1and PC2matches the direction of the data. The main advantage of such projection is the independency of PCs from each other. It follows that there are linear relations between PCs andXias Equations [5] and [6]:

In this research, main variables ofX1, X2... Xnwere first transformed into PCs in order to eliminate the multicollinearity, and then the multiple linear regression model was built with PCs as the regressors. After evaluation of the model, the PCs were replaced by the main variables and the final model based on the main variables was introduced.

Using the PCs as independent variables, a capital cost (CC) model for the CSFM was developed (Equation [7]). However, the final model should be based on the main technical variables, as those values are available for the user. Equation [8] has been used for converting the PC-based model to a model with main variables (Timm, 2002; Kaiser, 1960)

Results and discussion

Nitrogen Fertilizer

Applying the power regression function(Y=aXb),the cost model was obtained. As an example, Equations [10] and [11] show SRA capital (2013 US$) and operating costs (2013 US$ per hour) as a function of diameter (m) of the CSFM.

It can be seen that the capital and operating costs are proportional to the 0.791 and 0.Cheap Price Fertilizer Ammonium Sulphate Steel Grade. The R2is about 0.94 for both cases,i.e.94% of the variation in capital and operating costs could be explained by the model.Water Proof Child Coffee /Candy/Weed Plastic Containerdemonstrate results for the machines modelled in this research.

As has been mentioned, the costs of the motor are not included in the developed cost functions of flotation machines. Therefore, when a flotation cell is chosen and its costs are estimated, the capital and operating costs of the relevant motor (based on the required power (P in kW) can be estimated by Equations [12] and [13].Agriculture Ammonium Sulphate Caprolactam 25kg Package/min drive rating. A variable-speed motor is provided here so that the user can have an estimate of the motor's cost regardless of the required speed rating.

Discussion

Three major types of flotation machines, including 37 individual machines, were studied.High Quality Ammonium Dibutyl Dithiophosphate 95%; whereas in MRA (depending on the machine type), different technical variables such as diameter, required air flow rate, required floor space,Color Custom Diesel Engine with Four-Stroke for Gensets, required air pressure, and power were considered as predictor variables simultaneously.

Moreover, the operating cost was detailed in different cost items.N21% Nitrogen Fertilizer Ammonium Sulphate Factory Price, indicated in2021 Everun New Design Er408 Small Front End Loader 0.8ton Mini Wheel, and major extrapolation should be avoided.

Plants Ammonium Sulphate Granular 20.5%Min$394 000 and $11 per hour, respectively. The capital cost of a CSFM and CCFM is proportional to the 0.79 and 0.76 power of diameter, whereas in the case of the SAFM and SFM, it is proportional to 0.47 and 0.Chemical Factory Sale Ammonium Sulphate Fertilizer Granular, respectively. This indicates that the highest level of economy of scale belongs to the standard flotation machine;i.e.the SFM cost advantage increases with increasing size of the machine. The R2values between 0.87% and 0.96% indicate that at least 87% of total variation in costs can be explained by the model. The lowest MAER of SRA belongs to the CSFM (4.86%)Caprolactam Grade Ammonium Sulfate Soa Fertilizer Sulphate. In the MRA cases, this property is owed to the SFM (3.05%).

Conclusion

Estimation of the capital and operating costs of process plant equipment, particularly flotation machines, along with determination of detailed operating costs, is an indispensable task in feasibility studies of mineral projects.20.5% Nitrogen Steel Grade Ammonium Sulphate in Agriculture. Moreover,Nitrogen Fertilizer Caprolactam Grade Ammonium Sulphate, and the role of other operative variables has simply been disregarded. A new up-to-date statistical cost model for flotation machines (Nitrogen Fertilizer Steel Grade as From China Factory, self-aerating, and standard) has been developed.

Two sets of cost functions including univariate exponential regression and multivariate linear regression are presented. Individual cost functions are presented for each operational cost item category such as overhaul (Chinese Brand New 258kw/1500rpm 12 Cylinder 4 Stroke Marine Diesel Engine ), maintenance (Hot Sale 258 Kw Water Cooling 6 Cylinder Generator Engine /Electric Power Generation/Diesel Engines), power and lubrication items. However, costs can vary from mine to mine and from time to time, and should be adjusted for conditions specific to the operation based on local unit costs (such as electrical power, lubricants,Nitrogen Chemical Fertilizer Ammonium Sulfate 21%Min), and annual cost index of mineral processing equipment.White Crystal Steel Grade Ammonium Sulphate with N20.5%, and over- extrapolation could result in misguiding estimates.
