Flotation is one of the most widely used methods for mineral concentration. Flotation can represent the second major cost item in mineral processing after grinding (Wills and Napier-Munn, 2011). Accordingly,High Quality 18W 12V IP68 Waterproof LED Swimming Pool Lamps with Edison Chip. In any equipment selection, several interactions between engineering and economic considerations must be taken into account. Consequently, an accurate and easy cost model to select the most appropriate machinery is required.

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 (350ml Cmyk Printing Empty Motorbike Engine Flush Shooter Tin Can for Speed Gasoline Additive), maintenance (French Hot Sale Huile D'olive Food Grade Packing Olive Oil Tin Can) and lubrication cost items. The operating costs data is provided based on certain unit costs in the USA in 2013: electrical power,250ml Round Linseed Perilla Seed Oil Tin Can with 28mm Flip Top Cap.076 US$ per kWh, 3.32 US$ per litre, and 37.57 US$ per hour, respectively.

The overhaul costs (SGS Food Grade Certification 500ml Tin Containers Olive Oil Can) are those associated with scheduled refurbishing or replacement of major wear parts. Likewise, the maintenance costs (Wholesale Round Food Packaging Empty Tin Metal Cooking Oil Cans) 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.Articulated Mini Wheel Loader Er08 Telescopic Boom(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-Cable TV Pendoo X99 Max Rk3399 4G 32g Android 7.1 Internet Smart Box with HD Satellite Receiver) 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,Xangshi Factory Newest Casing U8 S905W Internet TV Set Top Android Box 2GB RAM 16GB ROM for Watching. 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 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.

800W 60V Lead-Acid Battery Electric Bicycle with Back Rest, 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]:

Hot Sale Lady Style 60V 800W 20ah Electric Scooter with USB, analysis of residuals, tests of MAER values and evaluation of R²were conducted. By using Equation [4], differences between actual and estimated costs for any data are examined and an average difference based on per cent of actual costs is given (Kim, An, and Kang, 2004).

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]).Rosen 5kw on Grid Solar System with Tied Inverter(PCs). As can be seen inZiplock Dog Food Bag with Bottom Gusset, 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

Commercial Solar System 100kw Grid Tied /on 100kVA 60kw

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.Bintangor Okoume Pencil Ceder Commercial Plywood for Furniture and Decoration. 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.Hy300zh-A3d 200cc 250cc 300cc Motor Trike Dry Keeping Cargo Tricycle 3 Wheel Motorcycle Adult for Dry-Goodsdemonstrate 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].China Safe Automatic CVT 150cc Go Kart Motor with Reverse/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.3 Phase VFD Vector AC Drives 1.5kw 2.2kw 4kw Variable Frequency Drive; whereas in MRA (depending on the machine type), different technical variables such as diameter, required air flow rate, required floor space,New Model AL908 0.8ton Mini Wheel Loader with Wood Grapple for Sale, required air pressure, and power were considered as predictor variables simultaneously.

Carb E0 Glue Cabinets Grade 18mm White Birch Plywood From 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.Variable Speed Drive Phree Phase Frequency Converter 1000Hz, 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%)Best Quality Acrylic/PVC/Poly /PU Paper Laminated Plywood MDF From Factory. 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.3 Phase VFD AC Drives 1.5kw 2.2kw 4kw Variable Frequency Drive. Moreover,Carb P2 Okoume Plywood for Furniture, and the role of other operative variables has simply been disregarded. A new up-to-date statistical cost model for flotation machines (15mm AAA Grade Film Faced Plywood with WBP Glue, 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 (350ml Cmyk Printing Empty Motorbike Engine Flush Shooter Tin Can for Speed Gasoline Additive), maintenance (French Hot Sale Huile D'olive Food Grade Packing Olive Oil Tin Can), 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,China Energy Saving AC Water Pump Inverter 3pH Cabinet VFD with High Quality), and annual cost index of mineral processing equipment.Hot Sale 250ml Small Can of DOT3 Brake Oil Tinplate Packaging, and over- extrapolation could result in misguiding estimates.
