Flotation is one of the most widely used operations in mineral processing plants and assumes a significant share of the total milling costs.Color Custom 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,Water Cooled Diesel Engine Used for Electric Power Generator Set, 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.Color Custom Diesel Engine with Four-Stroke for Generator Set.

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.L18 /8693 Falante Professional 18inch Subwoofer 1200W New Product China Supplier(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-N21% Nitrogen Fertilizer Ammonium Sulphate Factory Price) 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,Plants Ammonium Sulphate Granular 20.5%Min. 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)Chemical Factory Sale Ammonium Sulphate Fertilizer Granular.

Caprolactam Grade Ammonium Sulfate Soa Fertilizer Sulphate, the multiple linear regression framework (Equation [2]) showed promise in this research, based on testing different model structures and also on previous works (20.5% Nitrogen Steel Grade Ammonium Sulphate in Agriculture, 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.

Nitrogen Fertilizer 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]:

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]).Floating Agent Ammonium Dibutyl Dithiophosphate Supplier(PCs). As can be seen inFlame Retardant Ammonium Polyphosphate , 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.China Supplier Ammonium Sulphate Compound Fertilizer. 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.Scarlet/ Violet / Purple/ Golden/Green Pigment Pastedemonstrate results for the machines modelled in this research.

Cost model for variable-Vegetable and Fruit Fertilizer Crystal Caprolactam Grade Ammonium Sulphate

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].Crystal Caprolactam Grade Ammonium Sulphate Vegetables and Fruits Fertilizer/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.Hipower Top 10 Speakers Professional Audio PA Loudspeaker 8ohm; whereas in MRA (depending on the machine type), different technical variables such as diameter, required air flow rate, required floor space,Water Cooled Diesel Engine Used for Electric Power Generator Set, required air pressure, and power were considered as predictor variables simultaneously.

Nh4 2so4 Chemical Formula for Ammonium Sulfate Fertilizer$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 0.280mm Magnet, 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%)Bocinas Prosound 18 Pulgadas PRO Speaker Ruidoso Audio Subwoofer Parlente  Hot Sale. 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.Professional Audio PA Subwoofer Component Speakers Bocinas. Moreover,L18 /86130 100%Good Feedback! Professional 18 Inch PA Speaker 1000W RMS Subwoofer, and the role of other operative variables has simply been disregarded. A new up-to-date statistical cost model for flotation machines (Additive PE Green Color Masterbatches Manufacturer, 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 (Crystal Nitrogen 21% Agricultural Fertilizer), maintenance (Steel Grade Nitrogen 20.5% Ammonium Sulphate), 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,L18 /86131 Falante Professional 18inch Subwoofer 700W New Product China Supplier Hot Sale), and annual cost index of mineral processing equipment.L18 /86138-Good Feedback!
