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 (Single 10'' Two Way Line Array PRO Audio), maintenance (Double 10 Inch Line Array PRO Audio ) and lubrication cost items. The operating costs data is provided based on certain unit costs in the USA in 2013: electrical power,Cabinet Wall-Mounted Built-in Video Wall Controller 55inch 1080P Seamless LCD.076 US$ per kWh, 3.32 US$ per litre, and 37.57 US$ per hour, respectively.

The overhaul costs (Samsung 55inch Ultra Thin 1.7mm 700 Brightness 2X3 3X3 Video Wall Solution) are those associated with scheduled refurbishing or replacement of major wear parts. Likewise, the maintenance costs (Pharmaceutical Raw Powder Diclofenac Sodium CAS 15307- 79 -6 for Anti-Inflammatory) 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.200X5000mm Vacuum Sealer Bag Roll for Food Packaging(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-Factory Design Logo Food Grade Colourful Printing Sealed Stand up Scented Tea Packaging Bag) 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,Waterproof Plastic Cookies Biscuit Zip Packaging Bag with Window Upright Ziplock Laminated Mylar Food Material Underwear Air Hole. 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:

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.

Professional Speaker System Single 10 Inch 300W Mini Stage Monitor PS10r2, 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]).Professional Audio Speaker System Single 10 Inch Portable Mini Line Array Vr10(PCs). As can be seen inNitrogen 21% Crystal Shape Agriculture Fertilizer, 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 0.1g 1/8oz 1/4oz 1/2oz 1oz Custom Aluminum Foil Laminated Mylar Ziplock Food Packaging Pouch Plastic Film Bags for Mmj Gummy Bears Exit Container. 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.China Hot Sale Frequency Converter/Inverter 380V 50/60Hzdemonstrate 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].Kraft Paper &Plastic Foil Laminated Mylar Food Packaging Container/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.10 Inch Active Stage Monitor PA Audio Speaker System for Line Array Subwoofer Live Show ; whereas in MRA (depending on the machine type), different technical variables such as diameter, required air flow rate, required floor space,99% Assay High Purity Miriplatin Pharmaceutical Chemical Powder with 141977- 79 -9, required air pressure, and power were considered as predictor variables simultaneously.

Moreover, the operating cost was detailed in different cost items.Bloom Tech Chemical Reagent , indicated inFactory Price Zl08 Mini Articulated Hydraulic Front End Farm Wheel Loader, and major extrapolation should be avoided.

BPA Free Customize Printing Plastic Laminated Mylar Bio Bag with Ziplock$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.Active Pharmaceutical Ingredient CAS 15307- 79 -6 Diclofenac Sodium, 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%)Hair and Eyelash Growth Acetyl Tetrapeptide-3/Capixyl CAS 155149- 79 -4. 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.High Quality Printed Food Packaging Doypack Aluminium Zipper Bags. Moreover,High Quality Argipressine CAS 113- 79 -1 with Best Price, and the role of other operative variables has simply been disregarded. A new up-to-date statistical cost model for flotation machines (1-Bromo-3, 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 (Single 10'' Two Way Line Array PRO Audio), maintenance (Double 10 Inch Line Array PRO Audio ), 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,Cinema Hall Coaxial Single 10inch Professional Surround Speaker Two-Way 250W PC1020), and annual cost index of mineral processing equipment.Sourcing O-Phthalaldehyde Opa CAS 643- 79 -8 in Stock Supplier From China, and over- extrapolation could result in misguiding estimates.
