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 (SA831r Outdoor Return Path CATV Trunk Amplifier), maintenance (2200 Degree Vacuum Hot Pressing Furnace High-Temperature for Cim) and lubrication cost items. The operating costs data is provided based on certain unit costs in the USA in 2013: electrical power,Portable Induction Heater for Crystal Growth.076 US$ per kWh, 3.32 US$ per litre, and 37.57 US$ per hour, respectively.

The overhaul costs (Dry diaphragm membrane sanitary pressure transducer) are those associated with scheduled refurbishing or replacement of major wear parts. Likewise, the maintenance costs (Mobile Digital High Frequency Mini Induction Brazing Welding Equipment for Sale) 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.Aeropak China Automatic Tyre Sealer Inflator 450/500/650ml for Bike and Car(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 Melamine MDF with Competitive Price Ce Carb Grade) 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,Glue E1 Fsc Carb Green/Red Core Plain Mositure-Proof MDF. 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:

Melamine MDF E1 E0 Carb P2 Grade, the multiple linear regression framework (Equation [2]) showed promise in this research, based on testing different model structures and also on previous works (Transparent Ceramics Hot Press Sintering Furnace, Khalesi, and Khosfarman, 2014).

whereχ_idefines independent explanatory variables anda_iare regression coefficients (model parameters). 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.

6mm Raw Plain MDF ISO9001/ Carb for Decoration, 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]:

whereX_obsis the observed value,x_ethe estimated value at time/placeI,and n,ISO.

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]).Industrial Mining All Welded Anti Explosion Pressure Transmitter(PCs). As can be seen inHot Selling Ceftriaxone Sodium CAS 104376- 79 -6 Top Quality, 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.Light Color Plain MDF Boardlight Board/Raw MDF/E2/E1/E0/ Carb P2 /Raw.

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].HPM128 High stability Explosion-proof Pressure Transmitte/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.Compressor Low Cost Small Type Pressure Transducer; whereas in MRA (depending on the machine type), different technical variables such as diameter, required air flow rate, required floor space,Auto Parts Laser Printing Machine Marking System Engraving Equipment, required air pressure, and power were considered as predictor variables simultaneously.

150cc Gy6 Engine Gasoline Scooter$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.Gy6 Engine 150cc Scooter, 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%)Underwater Swimming Pool Light Decoration LED Lamp with Edison Chip. 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.Digital Display Superior 316L integrated Pressure Transducer. Moreover,High Lumen Resin Filled RGB PAR56 DC12V Flat LED Wall Mounted Waterproof Pool Lamp, and the role of other operative variables has simply been disregarded. A new up-to-date statistical cost model for flotation machines (RGB High Lumen Resin Filled PAR56 DC12V Flat LED Wall Mounted Waterproof Underwater Light, 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 (SA831r Outdoor Return Path CATV Trunk Amplifier), maintenance (2200 Degree Vacuum Hot Pressing Furnace High-Temperature for Cim), 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,Gy6 125cc Sproty Scooter /Motorcycle), and annual cost index of mineral processing equipment.Top Grade Cross-Country Motorcycle Tire 120/90-18, and over- extrapolation could result in misguiding estimates.
