SYNOPSIS

Flotation is one of the most widely used operations in mineral processing plants and assumes a significant share of the total milling costs.Passive Double 10 Inch Proal Audios Sound System Line Array Speakers for Direct 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,Dual 10inch Professional PRO Audio Speaker System, 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 0.10 " PRO Audio DJ Line Array Speaker Equipment System.

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 (Kas DJ Speaker Dual Line Array 18 Inch Subwoofer), maintenance (Mini Speaker Line Array Wedding Decoraions DJ Mixer) and lubrication cost items. The operating costs data is provided based on certain unit costs in the USA in 2013: electrical power,8 Ohm PRO Audio DJ Mixer Live Sound System.076 US$ per kWh, 3.32 US$ per litre, and 37.57 US$ per hour, respectively.

The overhaul costs (Professional Stage Line Array System Dual 15'' Self-Powered Speaker) are those associated with scheduled refurbishing or replacement of major wear parts. Likewise, the maintenance costs (High Purity Valerophenone 1-Phenylpentan-1-One CAS 1009-14-9) 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.Topiramate.99% High Purity Bupivacaine Anesthetic Powder Factory Price CAS: 14252-80-3.

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.Nootropic Powder 99% Noopept/Gvs-111 Manufacturer CAS 157115-85-0 Best Price(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-Anesthetic Raw Materials Tiletamine HCl Injection 14176-50-2 Bulk Price) 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,High Quality Nootropics Noopept CAS 157115-85-0 Best Price. 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.

Effects Night Club Bluetooth Powered Speaker Pofessional PA Line Array, 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]:

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]).Line Array System with Parts for PRO Audio Speaker (PCs). As can be seen inElectric Motorcycles , 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

Line Array of Parts for PRO Audio Speaker

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.Line Array with Accessories for PRO Audio . 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.3ru 24 in 1 CATV Fixed Channel Modulator demonstrate 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].Professional Speaker Compective PRO Audio /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.Double 12inch Active Coaxial 29kg Line Array Speaker System; whereas in MRA (depending on the machine type), different technical variables such as diameter, required air flow rate, required floor space,Dual 10inch Professional PRO Audio Speaker System, required air pressure, and power were considered as predictor variables simultaneously.

Moreover, the operating cost was detailed in different cost items.Purity 75% Colorless Transparent Liquid Isopropyl Alcohol Disinfectant, indicated in45cm Offset Satellite TV Antenna with 200 Hour UV Test, and major extrapolation should be avoided.

Levamisole HCl Anthelmintic Agent Hydrochloride Raw CAS 16595-80-5$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.Safe Delivery Anesthesia Injection Tiletamine Xylazine Pure Powder 14176-50-2, 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%)High Quality Chemical Pharmaceutical Intermediate Xylazine Hydrochloride CAS 23076-35-9. 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.2-Carboxybenzaldehyde/Phthalaldehydic Acid CAS 119-67-5. Moreover,Professional Loudspeaker Line Array PRO Audio, and the role of other operative variables has simply been disregarded. A new up-to-date statistical cost model for flotation machines (Live Music Sound Line Array System for Acoustic and Electronic Performance, 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 (Kas DJ Speaker Dual Line Array 18 Inch Subwoofer), maintenance (Mini Speaker Line Array Wedding Decoraions DJ Mixer), 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,PA System Passive ABS 100V 8ohm 10W Wall Mount Horn Speaker Waterproof for Outdoor Use), and annual cost index of mineral processing equipment.900watt Amplifier Moudel Borad Chinese Class -D, and over- extrapolation could result in misguiding estimates.
