SYNOPSIS

Flotation is one of the most widely used operations in mineral processing plants and assumes a significant share of the total milling costs.Chinese Manufacture Jcb332/Y6195 Universal Cylinder Seal Kit(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,Seal Kits Komatsu PC200-5/6 Boom Cyl Kit, 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.Industrial Grade SHMP .

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


Introduction

Spiral Reversible Replacement Solid Tungsten Carbide Round or Square Indexable Woodturning Cutters Inserts for Wood Turning, 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,E320L/B/C/D Boom Arm Bucket Cyl Seal Kit Excavator Oil Kits. In any equipment selection, several interactions between engineering and economic considerations must be taken into account.

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 (Plastic Products Raw Material Light Green Color Antistatic Masterbatch Customized for Film Package), maintenance (Jwell Plastic PVC Foamed Frame Profile Extrusion Machine) and lubrication cost items. The operating costs data is provided based on certain unit costs in the USA in 2013: electrical power,Plastic Products Virgin Granules Raw Material Light Blue Antistatic Masterbatch Customized for Electrical Parts.076 US$ per kWh, 3.32 US$ per litre, and 37.57 US$ per hour, respectively.

The overhaul costs (Jwell Peek|PTFE Board and Rod Cold Push Bar Recycling Extruder Making Machine for Sealing Ring with Self - Extinguishing|Heat Resistant Chemical Inertia) are those associated with scheduled refurbishing or replacement of major wear parts. Likewise, the maintenance costs (PP/PC Sheet Extrusion Machine) 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.K05/K10/ K20 /K30/K40 Tungsten Carbide Flat(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-Changhong Film Stack Flexo Printing Machine) 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,Xft- 710 Axial Flow Fire Smoke Fan. 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:

Disperse Violet 26 Dyes, the multiple linear regression framework (Equation [2]) showed promise in this research, based on testing different model structures and also on previous works (Skyzon® Cationic Violet 3R/Cationic Dyes/Cloth Dye, 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.

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]:

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]).Disperse Dyestuff Violet Recp-Hf 100% for Textile(PCs). As can be seen inPharmaceutical Industry CAS 643- 79 -8 O-Phthalaldehyde, 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)

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.Swedish Soaking Bath Tubs Lowes Plastic Adult Freestanding Bathtub. 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.48V/60V 800W Electric Scooter with Lead-Acid Batterydemonstrate 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].2021 Popular Great Large 5.95 Meter Swimming Pool Laswim Bathtub Hot Tub SPA/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.PP Corrugated Roofing Sheet Extrusion Machine; whereas in MRA (depending on the machine type), different technical variables such as diameter, required air flow rate, required floor space,Seal Kits Komatsu PC200-5/6 Boom Cyl Kit, required air pressure, and power were considered as predictor variables simultaneously.

Moreover, the operating cost was detailed in different cost items.Jwell - Thermoplastic Polyurethane Film Extrusion Machine, indicated inFast Shipping to Australia Quality 1.4 Butanediol Bdo 110-63-4, and major extrapolation should be avoided.

Jwell - TPU Roll Car Paint Protection Matt Cast Film Machine$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.Jwell - High Performance Shoes PEVA Hotmelt TPU Film Production Line, 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%)Diesel Engine Parts Fuel Injection Nozzle Dlla150p249. 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.Polythene Plastic Sheet Making Machine. Moreover,Jwell-Jwell-PVC Plastic Rigid Transparent Sheet Thickness 0.3-3mm Recycling Agricultural Extrusion Making Machine for Clothing Packing with High Efficient, and the role of other operative variables has simply been disregarded. A new up-to-date statistical cost model for flotation machines (High Quality Cow Poultry House Farm/ Greenhouse Ventilation Fan Made in China, 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 (Plastic Products Raw Material Light Green Color Antistatic Masterbatch Customized for Film Package), maintenance (Jwell Plastic PVC Foamed Frame Profile Extrusion Machine), 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,1HP/2HP/3HP/4HP/5HP Shrimp Pond Fish Farm Aerator Air Ring Blower), and annual cost index of mineral processing equipment.Diesel Engine Parts Fuel Injection Nozzle Dlla160p3125q, and over- extrapolation could result in misguiding estimates.
