SYNOPSIS

Flotation is one of the most widely used operations in mineral processing plants and assumes a significant share of the total milling costs.Tx6s H616 Allwinner 4K Smart Aluminum Ott IPTV 10.0 Android TV Box(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,2.5L-25L Square Metal Tin Can with Lid for Paint Glue Adhesives Packing, 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 0.1 Liter Metal Square Tin Can with Screw Lid for Oil Paint Chemical.

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

Methodology

Data

Thirty-seven major flotation machines (Hot Smart Electric Scooter 60V800W Power Motor with USB, 11 self-aerating, and 10 standard cells) are considered in this study. The data descriptions are presented inFactory Price Power Battery Motor E Scooter 60V 20ah 2000W Electric Motorcycle(InfoMine, 2013). InfoMine conducts annual surveys on costs of equipment from manufacturers and distributors; fuel, energy, and lubricant suppliers;Factory Direct Supply High Speed Electric Motorcycle Throttle Control Bike' names:

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 (60V/72V 1200W Electric Scooter with Tianneng Battery), maintenance (Best Price Solar Energy Systems Home Panel System 15kw 20kw on Grid) and lubrication cost items. The operating costs data is provided based on certain unit costs in the USA in 2013: electrical power,Customization Energy Solution 1kw 2kw 3kw 5kw 10kw 15kw 20kw 25kw 50kw on Grid/Grid Tied Solar Panel Power System.076 US$ per kWh, 3.32 US$ per litre, and 37.57 US$ per hour, respectively.

The overhaul costs (Metal Cans 0.925 Liter Tin Barrel for Packaging Container) are those associated with scheduled refurbishing or replacement of major wear parts. Likewise, the maintenance costs (Frequency Inverter Pump AC Drive Price) 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.Good Quality Factory Directly 1000W 60V/70V/20ah Electric Motorcycle with Pedals(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-0.5L Tin Can with Dry Cover) 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,Food Grade Container 1 Liter Square Olive Oil Latest Design Metal Tin Cans. 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:

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.

Cheap Power Motor Big Protect Frame Electric Scooter Motorcycle 60V800W, 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]).Hot Selling Electric City Bike New Scooter E-Scooter Motorcycle as Children's Gifts(PCs). As can be seen inChina Vector Control AC Drives / Frequency Inverter Manufacturer 3pH 250kw, 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.Wolf Wl80 Mini Radlader Hoflader with Forks in Farm. 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.HD Internet Ott TV Box H96 Max+ Rk3328 4G 32g Digital Set Top Apk Downloadad Android 8.1demonstrate 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].Big 4000W 70V Electric Scooter/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.4 Liter Rectangle Metal Tin Can for Olive Oil Package and Peanut with Flexible Spout; whereas in MRA (depending on the machine type), different technical variables such as diameter, required air flow rate, required floor space,2.5L-25L Square Metal Tin Can with Lid for Paint Glue Adhesives Packing, required air pressure, and power were considered as predictor variables simultaneously.

Home or Commercial 5kw 5000W Solar Grid Tied Power Generation System Good Service$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.Grid Tied 30kw Solar PV System for Shingle Roof, 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%)Good Quality Empty 1 Litre Metal Tin Paint Cans with Handle for Sale. 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.Pinergy Grid Tied Solar Panel System 6kw Energy 110V Single Phase. Moreover,off Grid 5kw 10kw Solar Power System, and the role of other operative variables has simply been disregarded. A new up-to-date statistical cost model for flotation machines (Pinergy 9kw on- Grid Tied Solar Power System for Home or Industrial Roof, 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 (60V/72V 1200W Electric Scooter with Tianneng Battery), maintenance (Best Price Solar Energy Systems Home Panel System 15kw 20kw on Grid), 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,2013 Popular Electric Motorcycle 90km with Pedal CE ), and annual cost index of mineral processing equipment.Chinese Zl08f Wheel Loader 0.8ton Mini with Quick Hitch for Sale, and over- extrapolation could result in misguiding estimates.
