Artisanal and Small-Scale Gold Mining Without Mercury | US EPA

This process is mostly used in large scale mining operations but has been increasingly adopted in small scale mining because of its high gold recovery rate and low cost. The best practices for chemical leaching are a combination of pre-concentration and mill leaching, as they lead to the least amount of waste, a short processing time for miners ...

Abstract - USGS

Working capital, based on 2 months of operating costs, was included in the capital cost of each mine and mill model. Working capital covers the cost of meeting operating costs in the initial stages of production, before revenue is generated from the first shipments of product (concentrates or dote).

Mineral Processing Plant Design

Capital Cost Direct Costs. The largest primary gyratory crushers cost US $2 million or more, while overall crushing plant costs can be as high as $18 million. It's necessary therefore to estimate crusher installation costs based on equipment costs plus the following direct costs, including construction contractor indirects: • Earthworks


Fixed costs make up a greater share of total costs in operations where labor is at a minimum. Variable costs increase primarily because of increased labor costs associated with bagging and warehousing. Analyses in this study give definite indications of economies of size. Costs are synthesized for output ranging from 40 to 100 percent of capacity.
