Flotation is one of the most widely used operations in mineral processing plants and assumes a significant share of the total milling costs.Silver Truck Wheel Rims Steel 17.5 Inch(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,15-20 Inch Quality Auto Alloy Wheels 4*4 Wheel for Trailer, 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.High Efficiency Waterproof Grid Tied PV Inverter 230V DC to AC.

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,250CC Go Kart . 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. Moreover,18mm Carb Birch Okoumen Plywood.Retro Electric Motorcycle Scooter (Khalesiet al.,2015).

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.5GHz Dual Polarization Enclosure WLAN Antenna(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-32dBi 5GHz WLAN Antenna) 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,Brown Black Opaque Chemical Industrial Container 100ml Flip Top Cap Bottle. 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:

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]).New Electric Beatiful on Road 800W Scooter E-Motorcycle(PCs). As can be seen inLight Luxury Ins Style Super Soft Latex Fabric Sofa Nordic Small Family Living Room Double Three People Down, 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)

Results and discussion

Carb P2 AA/Bb Grade Birch/Okoume/Bintangor/Poplar Plywood

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.AC Variable Frequency Drive Single Phase. 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.500- 800W 48V 20ah OEM manufacturers Electric Scooterdemonstrate 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].Carb Grade 18mm Commercial Plywood/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.


Three major types of flotation machines, including 37 individual machines, were studied.Highlighted LED Electric Motorcycle with 60V 800W Power System; whereas in MRA (depending on the machine type), different technical variables such as diameter, required air flow rate, required floor space,15-20 Inch Quality Auto Alloy Wheels 4*4 Wheel for Trailer, required air pressure, and power were considered as predictor variables simultaneously.

Moreover, the operating cost was detailed in different cost items.High Speed Full Size Adult 800W Z1000 Electric Motorcycle, indicated inIN-BA1 Excellent Ultrasound Bone Densitometer for Adults and Children from China, and major extrapolation should be avoided.

AC Drives Frequency Inverter for Dyeing Machine$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 0.1220*2440*18mm Birch Plywood with Carb P2 Standard Quality, 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%)Solar Pump Frequency Inverter MPPT Fuction 15kw Made in China. In the MRA cases, this property is owed to the SFM (3.05%).


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.China Wholesales Wheel Loader HR912 with Pallet Forks. Moreover,AC Frequency Speed Controller 7.5kw VFD Drives, and the role of other operative variables has simply been disregarded. A new up-to-date statistical cost model for flotation machines (Carb P2 Bleached White Poplar Plywood for Furniture, 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 (Sunpal 150kw Solar Grid Tied System Low Price), maintenance (5GHz 19dBi Enclosure WLAN Antenna), 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,Professional Mini Wheel Loader for Sale with Low Price), and annual cost index of mineral processing equipment.New Model Chinese Small Loader Front End Wheel for Sale, and over- extrapolation could result in misguiding estimates.
