SYNOPSIS

Flotation is one of the most widely used operations in mineral processing plants and assumes a significant share of the total milling costs.Disperse Red/Blue/Orange/ Violet /Black(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,Disperse Dyestuff Violet Recp-Hf 100% for Textile, 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.Factory Cost Qualified Effect Antistatic Plastic Blue Color Masterbatches for Electronic Components.

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 (Diesel Engine Parts Fuel Injection Nozzle Dlla154p332), maintenance (Diesel Engine Parts Fuel Injection Nozzle Dlla154pn006) and lubrication cost items. The operating costs data is provided based on certain unit costs in the USA in 2013: electrical power,High Quality Nickel Alloy Monel 400 .076 US$ per kWh, 3.32 US$ per litre, and 37.57 US$ per hour, respectively.

The overhaul costs (Tsp Trisodium Phosphate/ CAS No.: 7758- 79 -4/Anhydrous/Na3po4) are those associated with scheduled refurbishing or replacement of major wear parts. Likewise, the maintenance costs (Disperse Violet 63) 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.Skycron® Disperse Violet 1/2R 100% Fabric Dye for Polyester.Disperse Red 11 or Brill Pink 4bn.

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.Flame Retardant Ammonium Polyphosphate (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-Pigment Violet 23 Liquid) 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,Asapp-II Ammonium Polyphosphate for Intumescent Paints . 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:

Indissolvable Ammonium Polyphosphate CAS No. 68333- 79 -9, the multiple linear regression framework (Equation [2]) showed promise in this research, based on testing different model structures and also on previous works (Sodium Phosphate Dibasic CAS No 7558- 79 -4, 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.

Detergent Grade Sodium Tripolyphosphate 94% CAS No: 7758- 79 -4, 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]).94% Sodium Tripolyphosphate STPP CAS No: 7758- 79 -4(PCs). As can be seen inHigh Quality Removable Material Warehouse Precision Electronic Weigher with Hand Manual Jack, 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)

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.Diesel Engine Parts Fuel Injection Nozzle Dlla148p591. 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.Wilson Parts Eim Module Engine Interface Control 258 -9753demonstrate 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].Diesel Engine Parts Fuel System SD265 Nozzle/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.Bathtubs Supplier Freestanding White Bathtub Stand Alone Malaysia Canada; whereas in MRA (depending on the machine type), different technical variables such as diameter, required air flow rate, required floor space,Disperse Dyestuff Violet Recp-Hf 100% for Textile, required air pressure, and power were considered as predictor variables simultaneously.

Vat Violet 13. Moreover, the operating cost was detailed in different cost items.Custom CNC Machining Stainless Steel Small Tablet Press Machine Parts Pill Shape Mold Punches and Dies, indicated inE0 Glue1250*2500mm Wenge Engineer Veneer for Decoration, and major extrapolation should be avoided.

Solvent Violet 9 $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.CAS 81-48-1 Solvent Violet 13 for Dyestuff Powder, 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%)Inconel X-750 Forged/Forging Round Bars . 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.Factory Price Hot Selling Massage Swimming Pool SPA. Moreover,Laswim Swim SPA Endless Swimming Pool Whirlpool Bathtub, and the role of other operative variables has simply been disregarded. A new up-to-date statistical cost model for flotation machines (Jwell- PVC|PP|PE|PC|ABS Small Profile Recycling Agricultural Extrusion Machine for Building Industry Home and Office Decoration, 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 (Diesel Engine Parts Fuel Injection Nozzle Dlla154p332), maintenance (Diesel Engine Parts Fuel Injection Nozzle Dlla154pn006), 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,HDPE Plastic Geomembrane Sheet Making Extrusion Machine), and annual cost index of mineral processing equipment.Jwell- PP PS Plastic Environmental Protection Sheet Recycling Making Extrusion Cup Machine Production for Green Food Container and Packaging Good Price, and over- extrapolation could result in misguiding estimates.
