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,with Built-in LiFePO4 Energy Storage Portable Generator 3.8kwh 80A Enjoys 2 Years Warranty. 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 (Real Mink 3D 5D New Fashion Fast Shipping High Quality Best Seller Eyelash), maintenance (High Quality Economic Ultrasound a/B Scan for Ophthalmology ) and lubrication cost items. The operating costs data is provided based on certain unit costs in the USA in 2013: electrical power,Ut-O500 Diagnosis System Portable Full Digital Ophthalmic Ultrasound a/B Scan for Eye.076 US$ per kWh, 3.32 US$ per litre, and 37.57 US$ per hour, respectively.

The overhaul costs (Ophthalmic a Scan and Pachymeter Combined Unit) are those associated with scheduled refurbishing or replacement of major wear parts. Likewise, the maintenance costs (Ophthalmic Optical Pachymeter & Biometer / a Scan ) are associated with both unscheduled repairs and scheduled servicing of all of minor and major components, excluding overhaul actions and lubrication. The cost of operator's time was not included in this study.1000MHz FTTH Trunk Line CATV Mini 2 Ports Signal Amplifier.Roadside Emergency Set Auto Car Tool Kit.

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.Portable Induction Heater for Crystal Growth(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-Dry diaphragm membrane sanitary pressure transducer) 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,Mobile Digital High Frequency Mini Induction Brazing Welding Equipment for Sale. 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:

whereYrefers to capital or operating costs,Xdefines an independent variable (one of the machine predictor variables), andaandbare constant values (parameters)High Frequency Induction Heater .

Industrial Vacuum Atmosphere Hot Pressing Sintering Furnace, the multiple linear regression framework (Equation [2]) showed promise in this research, based on testing different model structures and also on previous works (Softel 4u 12 Channel Agile CATV Analog RF Modulator, Khalesi, and Khosfarman, 2014).

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.

Maintence Grease Gun 21V LCD Real Time Information Reading Hand Tool, 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]:

High Quality Melamine MDF with Competitive Price Ce Carb Grade, 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]).The Best Sale and Low Price Chinese Brake Lathe (PCs). As can be seen inFast Delivery CAS 525- 79 -1 6-Furfurylaminopurine 99% with Best Price, 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.HPM410W Submerged Integrated Level Sensor Transmitter. 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.Mini Radlader with Ce for Germany and Sweden Marketdemonstrate 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].Coconut Shell Carbon Charcoal Making Machines Production Line/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.2440mmx1220mmx3mm Carb P2 Formaldehyde Raw HDF Board; whereas in MRA (depending on the machine type), different technical variables such as diameter, required air flow rate, required floor space,20/30/50/60/100W Raycus Max Jpt Ipg Table 3D CO2 Mopa Color Logo Printer Marker Fiber Laser Marking Machine, required air pressure, and power were considered as predictor variables simultaneously.

Moreover, the operating cost was detailed in different cost items.Light Color Plain MDF Boardlight Board/Raw MDF/E2/E1/E0/ Carb P2 /Raw, indicated inManufacturer Supply Bdo Novel Intermediate 1, and major extrapolation should be avoided.

Glue E1 Carb Plain Mositure-Proof MDF$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.Melamine MDF 2440mmx1220mmx3.0mm with Carb P2 Certification, 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%)Draught Fan Digital LED Micro Air Wind Pressure Sensor. 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.HPM128 High stability Explosion-proof Pressure Transmitte. Moreover,Compressor Low Cost Small Type Pressure Transducer, and the role of other operative variables has simply been disregarded. A new up-to-date statistical cost model for flotation machines (Hot Sale Motorcycle with 150cc Gy6 Engine, 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 (Real Mink 3D 5D New Fashion Fast Shipping High Quality Best Seller Eyelash), maintenance (High Quality Economic Ultrasound a/B Scan for Ophthalmology ), 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,HPM766 Dry diaphragm membrane sanitary pressure transducer), and annual cost index of mineral processing equipment.150cc Gy6 Engine Gasoline Scooter, and over- extrapolation could result in misguiding estimates.
