SYNOPSIS

Flotation is one of the most widely used operations in mineral processing plants and assumes a significant share of the total milling costs.Mini Wheel Loader Er08 with Hydrostatic Transmission System for Sale(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,30kw Grid Tied Solar Power System Home Popular in Philippines, 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.New Condition Large Capacity Mini Truck Dumper.

Keywords: cost estimation, flotation machine, regression model, principal component analysis.

Introduction

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 (High Effective Automatic Ultrasound Bone Densitometer), maintenance (Low Price Ophthalmic a-Scan Ultrasound with Pachymeter Ho-100) and lubrication cost items. The operating costs data is provided based on certain unit costs in the USA in 2013: electrical power,MS-3100) Portable Full Digital Ophthalmic Ultrasound a/B Scan Pachymeter Biometer.076 US$ per kWh, 3.32 US$ per litre, and 37.57 US$ per hour, respectively.

The overhaul costs (4.8kwh Multi-Function Solar Energy Lithium Battery Ion for Home Portable Power Generators) are those associated with scheduled refurbishing or replacement of major wear parts. Likewise, the maintenance costs (Lithium Prismatic Cells 40V 60V 72V LiFePO4 Battery Li-ion for Solar and EV) 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.Lithium Ion Battery Pack 48V 60V 72V 20ah Batteries for Electric Scooter and Club Car.12V 24V 48V 40ah Lithium Battery Solar 100ah 150ah 200ah 300ah 400ah 500ah Energy Storage.

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.5L Vegetable Cooking Oil Custom Tinplate Square Can(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-Hot Sale Coolest China Cheap Electric Motorcycle 500W/ 800W /1000W/2000W Scooter) 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,Wholesale Plastic Square 1 Liter Fertilizer 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:

50cc Motorcycle, the multiple linear regression framework (Equation [2]) showed promise in this research, based on testing different model structures and also on previous works (Vdf AC DC Drive Solar Power Inverter Converter Using for Tower Lift 250kw, 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.

Zhenhua Classic Motorcycle Dax 125cc Euro4, 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]:

Wholesale 1L Round Empty Fully Synthetic Brake Oil Tin Can with Metal or Aluminum Caps, 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]).5GHz Dual Pol Sector Antenna with Enclosure(PCs). As can be seen inChinese Cheap 1000W 2 Wheel Mobility Scooter Electrical Moped Motorcycle for Adult, 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.Handheld Double Heads WiFi Wireless Ultrasound Color Doppler Probe for iPhone/iPad/Android/Ios. 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.Chinese Heavy Truck Diesel Engine Pump Cylinder 161500137712demonstrate 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].800W 72V China Electric Tricycle for Handicapped/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.Two Wheel Adult Automatic 800W 48V Lithium Battery Electric Motorcycle with Pedals; whereas in MRA (depending on the machine type), different technical variables such as diameter, required air flow rate, required floor space,30kw Grid Tied Solar Power System Home Popular in Philippines, required air pressure, and power were considered as predictor variables simultaneously.

5GHz Antenna High Gain 16dBi Panel. Moreover, the operating cost was detailed in different cost items.2021 New Design Switch Control 12V 18W Wall Mounted LED Swimming Pool Light Underwater with CE RoHS IP68 Reports, indicated inDecorative Pine Groove Plywood Veneer Fancy, and major extrapolation should be avoided.

5GHz 29.5dBi Die Cast Grid Antenna$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.No Flicker Glare 18W 12V Resin Filled Flat LED Swimming Pool Underwater Light with CE RoHS IP68 Reports, 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%)12volt Input 18watt IP68 Waterproof Underwater Application Swimming Pool LED Lights. 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.5GHz 23dBi Dual Polarized Panel Antenna . Moreover,5GHz 27dBi Enclosure WiFi Antenna, and the role of other operative variables has simply been disregarded. A new up-to-date statistical cost model for flotation machines (TUV Certificate Gried Tied on Grid 20kw Solar PV System, 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 (High Effective Automatic Ultrasound Bone Densitometer), maintenance (Low Price Ophthalmic a-Scan Ultrasound with Pachymeter Ho-100), 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,High Quality 18W 12V Resin Filled Flat LED Swimming Pool Underwater Light with Edison Chip), and annual cost index of mineral processing equipment.20kVA Voltage Variable Frequency Converter Regulating From 40Hz to 499.9Hz 0-520V, and over- extrapolation could result in misguiding estimates.
