Operating costs for flat-rolled mini-mill producers have dropped in 2019 as weaker steel markets have pulled down metallics prices. This has meant that operating costs for mini-mills are now in line with integrated producers in the USA. However, the current cost level is not expected to be maintained. US mini-mills are typically higher cost.
Potential cost savings measures. This study has found that in general the relative Mining and Milling costs of a given operation do not significantly differ, and generally fall within the range of 43:43:14 to 45:45:10 (Mine:Mill:G & A). In addition, G & A costs were found to be consistently lower than both Milling and Mining costs.
C up (t)is the cost of under production, Tt up is the tonnage of under produced ore, gt( )is the average input grade to the mill, Rt p ( )is the recovery of processing, Pt( ) is the commodity price, Ct p is the cost of processing in period t and i is the interest rate. This approximation for the cost of under production assumes that under production will lead to a

An economic analysis model is proposed for estimating the cost savings incurred in all operations, from blasting to milling, in a copper mine using spectral imaging-based tracking. A conventional mid-sized copper mine in Arizona with two ore types is used as a case study. First, a combined regression and discrete event simulation model of the ...
