Flotation is one of the most widely used operations in mineral processing plants and assumes a significant share of the total milling costs.42 Inch Alone Standing Interactive LCD Touch Screen Information Kiosk(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,55 Optional Inch Outdoor Stand Double-Side Alone Digital Signage LCD Advertising Display, 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 0.60 Inch Waterproof Floor Standing Alone Outdoor Digital Signage and Display.

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,Sinopec Brand Chemical Fertilizer N21% with White Color. 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,White Ammonium Sulphate NPK Fertilizer.Nitrogen 21% Crystal Shape Agriculture Fertilizer(Khalesiet al.,2015).

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 (Caprolactam Grade Ammonium Sulfate Soa Fertilizer Sulphate), maintenance (20.5% Nitrogen Steel Grade Ammonium Sulphate in Agriculture) and lubrication cost items. The operating costs data is provided based on certain unit costs in the USA in 2013: electrical power,Nitrogen Fertilizer Caprolactam Grade Ammonium Sulphate.076 US$ per kWh, 3.32 US$ per litre, and 37.57 US$ per hour, respectively.

The overhaul costs (Nitrogen Fertilizer Steel Grade as From China Factory) are those associated with scheduled refurbishing or replacement of major wear parts. Likewise, the maintenance costs (Nitrogen Chemical Fertilizer Ammonium Sulfate 21%Min) 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.China Suppllier Ammonium Sulphate 21% Nitrogen Fertilizer(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-Granular Ammonium Sulphate) 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,Fertilizer N21%. 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:

whereYrefers to capital or operating costs,Xdefines an independent variable (one of the machine predictor variables), andaandbare constant values (parameters)China Supplier Ammonium Sulphate Compound Fertilizer.

Crystal Fertilizer Ammonium Sulphate for Coumpound, the multiple linear regression framework (Equation [2]) showed promise in this research, based on testing different model structures and also on previous works (Raw Material of Making Compound Fertilizer Ammonium Sulfate N1%, 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.

Vegetable and Fruit Fertilizer Crystal Caprolactam Grade Ammonium Sulphate, 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]:

Hipower Top 10 Speakers Professional Audio PA Loudspeaker 8ohm, 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]).650W-18 Inch Subwoofer Speaker Manufacture China Factory Directly(PCs). As can be seen inTrade Peak Lowest Price for 150cc ATV, 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)

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].OEM Custom Square Rectangle Round Rubber Cover/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.


Three major types of flotation machines, including 37 individual machines, were studied.N21% White Granular Ammonium Sulphate; whereas in MRA (depending on the machine type), different technical variables such as diameter, required air flow rate, required floor space,55 Optional Inch Outdoor Stand Double-Side Alone Digital Signage LCD Advertising Display, required air pressure, and power were considered as predictor variables simultaneously.

Vegetable and Fruit Fertilizer Ammonium Sulfate Nitrogen 21%. Moreover, the operating cost was detailed in different cost items.Agriculture Fertilizer N 21% Ammonium Sulfate, indicated inGenerator Interface Module Eim Basic 258 -9753 for Fg Wilson Engine, and major extrapolation should be avoided.

21% Fertilizer Ammonium Sulphate Caprolactam Grade Crystalline$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.Agriculture Fertilizer Nitrogen 21% Ammonium Sulfate China Factory, 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%)Power Steel Grade Nitrogen 20.5% Industrial Ammonium Sulphate Chemical Fertilizer. In the MRA cases, this property is owed to the SFM (3.05%).


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.White Extrusion Granular Ammonium Sulphate China Factory. Moreover,Granular Grade Ammonium Sulphate N20.5% Nitrogen Fertilizer, and the role of other operative variables has simply been disregarded. A new up-to-date statistical cost model for flotation machines (Nitrogen Fertilizer Color Granular Ammonium Sulphate 20.5+24s, 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 (Caprolactam Grade Ammonium Sulfate Soa Fertilizer Sulphate), maintenance (20.5% Nitrogen Steel Grade Ammonium Sulphate in Agriculture), 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,China Suppliers Alone Type Wraped Beam Disc Machenism Padlock), and annual cost index of mineral processing equipment.Dust Proof Steel Shackle Padlocks with Master Key, and over- extrapolation could result in misguiding estimates.
