SYNOPSIS

Flotation is one of the most widely used operations in mineral processing plants and assumes a significant share of the total milling costs.CAS: 74- 79 -3 Amino Acid L-Arginine(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,Glycolic Acid Cosmetic Grade CAS 79 -14-1 /a-Hydroxyacetic, 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.St-10kw/kVA Single Phase Brush Type Electric Generator.

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

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 (Super Quality and Best Price Nitrogen Fertilizer Ammonium Sulfate N21%), maintenance (Water Cooled Diesel Engine Color Custom for Power Generator Set) and lubrication cost items. The operating costs data is provided based on certain unit costs in the USA in 2013: electrical power,Direct Injection Diesel Engine with 6-Cylinder 4-Stroke Used for Electric Generator Sets.076 US$ per kWh, 3.32 US$ per litre, and 37.57 US$ per hour, respectively.

The overhaul costs (Nitrogen Fertilizers Agriculture N20.5% Granular Ammonium Sulphate) are those associated with scheduled refurbishing or replacement of major wear parts. Likewise, the maintenance costs (China Weichai Steyr 258 -450kw Marine Diesel Engine Wp6 Boat with High Quality) are associated with both unscheduled repairs and scheduled servicing of all of minor and major components, excluding overhaul actions and lubrication. The cost of operator's time was not included in this study.White Crystalline Ammonium Sulphate for Compound Fertilizer.Deisel Engine for Silent Power Generator with 6-Cylinder. Here,in Line Multy-Cylinder Diesel Engine for Power Generator Set, separate capital and operating cost functions for variable-6-Cylinder Diesel Engine Water Coolant for Electric 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.in Line Direct Injection Diesel Engine Used for Generator Set(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-Color Custom Diesel Engine with Four-Stroke for Gensets) 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,6-Cylinder Diesel Engine with Four-Strke for Silent Generator Set. 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:

Direct Injection Water Cooled Diesel Engine for Generator Set, the multiple linear regression framework (Equation [2]) showed promise in this research, based on testing different model structures and also on previous works (Water Cooled Cylinder Diesel Engine Used for Generator Set, Khalesi, and Khosfarman, 2014).

As was mentioned, independency ofx_ivariables 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 21% Granular Fertilizer 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]).Wholesale Ammonium Sulphate with SGS and Coa Certificate(PCs). As can be seen inProfessional Powered Line Array Selfpowered Speakers Active 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 andX_ias Equations [5] and [6]:

In this research, main variables ofX₁, X₂... X_nwere 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

Competitive Pice N21% Caprolactam Ammonium Sulphate 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.Water Cooling Diesel Engine with 6-Cylinder for Power Generator. 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.White Color Crystal Nitrogen N21% Ammonium Sulfatedemonstrate 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].Direct Injection Water Cooled Diesel Engine Used for Generator Set/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.Waterproof Floor Standing Alone Outdoor Digital Signage; whereas in MRA (depending on the machine type), different technical variables such as diameter, required air flow rate, required floor space,Glycolic Acid Cosmetic Grade CAS 79 -14-1 /a-Hydroxyacetic, required air pressure, and power were considered as predictor variables simultaneously.

Color Custom Direct Injection Diesel Engine Used for Generator Set. Moreover, the operating cost was detailed in different cost items.Water Cooled Diesel Engine Used for Electric Power Generator Set, indicated inDexketoprofen Trometamol Manufacturer CAS 156604- 79 -4 with Purity 99%, and major extrapolation should be avoided.

Color Custom Diesel Engine with Four-Stroke for Generator Set$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.Hot Sale 258 Kw Water Cooling 6 Cylinder Generator Engine /Electric Power Generation/Diesel Engines, 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 Used for Silent Generator Set with Multy-Cylinder. 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.Waterproof Floor Standing Alone Outdoor Digital Signage Display. Moreover,Chinese Brand New 258kw/1500rpm 12 Cylinder 4 Stroke Marine Diesel Engine , and the role of other operative variables has simply been disregarded. A new up-to-date statistical cost model for flotation machines (Hot Sale 258 Kw Water Cooling 6 Cylinder Generator Engine /Electric Power Generation/Diesel Engines, 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 (Super Quality and Best Price Nitrogen Fertilizer Ammonium Sulfate N21%), maintenance (Water Cooled Diesel Engine Color Custom for Power Generator Set), 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,43" Indoor Narrow Bezel Floor Standstand Alone and Networked LCD Advertising Display Digital Signage), and annual cost index of mineral processing equipment.49 Inch Portable Alone Standing LED LCD Poster Digital Menu Board, and over- extrapolation could result in misguiding estimates.
