Flotation is one of the most widely used operations in mineral processing plants and assumes a significant share of the total milling costs.High Performance Motorcycle Tire for Senegal (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,Double Rear Tyre Tricycle with 300cc Water Cooling Engine, 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 0.300cc Gas Aluminum Adult Tricycle Reverse Truck Cargo .

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

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.Solar Energy System 3kwh Power Home Built in Inverter(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-High Quality 3kwh Rechargeable LiFePO4 Lithium Battery) 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,Automatic Thermostatic Vulcanizer for Sale . 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)BMW N63 S63 Camshaft Alignment Tool Set .

Gy6 -125 Spark Plug Cap OEM Quality Motorcycle Parts, the multiple linear regression framework (Equation [2]) showed promise in this research, based on testing different model structures and also on previous works (2021 High Quality Marine 1400W Hybrid Power Inverter Solar System Portable with 3kwh Lithium Battery, 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.

Motorcycle Scooter Rear Clutch Assembly for Gy6 -90 Engines, 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]).Cheap Popular Pattern 3.00-18 Motorcycle Tyre(PCs). As can be seen inWl80 Mini Loader with Yanmar Engine, 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)

Results and discussion

Discount High Strength 90/90-19 Motorcycle Tyre/Tire

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.New Pattern Best Price 110/90- 17 Motorcycle Tire. 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.St-2kw 230V/50Hz Single Phase Brush Alternator for Saledemonstrate 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 Hot Sale Surface Mounted Swimming Pool Underwater LED Light with Edison Chip/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.Chinese 300cc Cheap Farm Gas Trike ; whereas in MRA (depending on the machine type), different technical variables such as diameter, required air flow rate, required floor space,Double Rear Tyre Tricycle with 300cc Water Cooling Engine, required air pressure, and power were considered as predictor variables simultaneously.

Moreover, the operating cost was detailed in different cost items.Thin-film Sputtering Pressure Transmitter For Medical Equipment, indicated inProfessional Sound System Effects for Equipment Hire , and major extrapolation should be avoided.

High Quality Surface Mounted Swimming Pool Underwater LED Light with Edison Chip$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.Ophthalmic Ultrasonic Pachymeter and Biometer, 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%)2D Echo Color Doppler Ultrasound Scanner Diagnostic Equipment. 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.2021 New Arrival Malaysian Eyebrow. Moreover,18" Remy Hair Lace Front Closure Natural Color Body Wave, and the role of other operative variables has simply been disregarded. A new up-to-date statistical cost model for flotation machines (250ml 500ml 750ml 1L Fancy Small Cooking Oil Tin, 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 (Customized 1L Round Empty Metal Oil Paint Package Tin/Can Container), maintenance (HDPE Pesticide Bottle 500ml 1L Foliar Fertilizer Plastic), 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,2D Echo Color Doppler Ultrasound Scanner), and annual cost index of mineral processing equipment.Ready to Ship Best Quality Brazilian Human Hair Body Wave Extensions, and over- extrapolation could result in misguiding estimates.
