SYNOPSIS

Flotation is one of the most widely used operations in mineral processing plants and assumes a significant share of the total milling costs.1500W Electric Motorcycle(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,High Speed Electric Motorcycle Scooter, 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.Bl-Xgz Electric Motorcycle.

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 (Everun 0.8ton Chinese Articulated Mini Wheel Loader), maintenance (Yn725 Yineng Mini Wheel Loader 1t 0.5cbm Capacity) and lubrication cost items. The operating costs data is provided based on certain unit costs in the USA in 2013: electrical power,500ml Round Resealable Tin Can with Easy Open Screw Top Lid.076 US$ per kWh, 3.32 US$ per litre, and 37.57 US$ per hour, respectively.

The overhaul costs (Compact wheel loader snow pusher landscaping) are those associated with scheduled refurbishing or replacement of major wear parts. Likewise, the maintenance costs (Factory Price Power Battery Motor E Scooter 60V 20ah 2000W Electric Motorcycle) 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.Adult Electric Motorcycle/Electric Bike/E-Bike W Waterproof with Double Disc Brakes/2 Wheel Scooter(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-China Single Phase Variable Frequency Inverter AC 220V) 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,Adult Electric Motorcycle/Scooter 60V20ah Lithium Battery China. 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:

AC Drive Frequency Variable General Power Supply Solar Motor Pump, the multiple linear regression framework (Equation [2]) showed promise in this research, based on testing different model structures and also on previous works (Pipo X8 PRO Win 10 Android 5.1 Z8350 Support Bluetooth 4.0 7 Inch Tablet PC, 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.

500kw Solar Energy System Grid Tied 500kwatt Panel Station, 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]).Planer Using VFD AC Drive Frequency Inverters 3pH 380V 11kw(PCs). As can be seen inTop Quality Tretinoin Powder  Retinoic Acid for Skin Care, 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

Solar Energy System 5kw Panel Home Grid Tied Power

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.Professional Electric Adult Motorcycle 70km/H Cheap Fast Coc Design. 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.Free Sample Ortho Phthalaldehyde 643- 79 -8 with Fast Delivery Manufacture in Chinademonstrate 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].Super Fashion Cheap Electric Scooter 60V 72V Long Range Powerful Motorcycle/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.Empty Gal Metal Round Tin Can 118ml 4oz Bundi PVC Pipe Glue Bottle with Brush; whereas in MRA (depending on the machine type), different technical variables such as diameter, required air flow rate, required floor space,High Speed Electric Motorcycle Scooter, required air pressure, and power were considered as predictor variables simultaneously.

Moreover, the operating cost was detailed in different cost items.High Speed CKD SKD Pedals Disc Brake Electric Motorcycle Scooter for Olderly or Adult, indicated inHome Solar Energy Storage System 3.2V Battery Bank LiFePO4 100ah 50ah 20ah 10ah Lithium Pack, and major extrapolation should be avoided.

Adult Electric Motorcycle with Lithium Battery China$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.Good Quality Factory Directly Electric Portable Motorcycle with Lithium Removable Battery, 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%)Hot Sale Factory Direct Supply 60/72V Electric Scooter Green Power Adult E-Motorcycle. 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.Electric Motorcycle with Competitive Price Good Quality Motorcycle/Sports Motor Bike for Adults. Moreover,Solar Inverter Pump Inverters 5.5kw, and the role of other operative variables has simply been disregarded. A new up-to-date statistical cost model for flotation machines (10 Liter Customized Printed Square Metal Fuel Oil Tin Cans for Paint Coating Solvent, 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 (Everun 0.8ton Chinese Articulated Mini Wheel Loader), maintenance (Yn725 Yineng Mini Wheel Loader 1t 0.5cbm Capacity), 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,350ml Brake Fluid Glue Tin Bottle), and annual cost index of mineral processing equipment.9L Tight Head Tin Can with Tap for Oilve Oil Ink and Paint, and over- extrapolation could result in misguiding estimates.
