By using the heuristic model, cost savings per ton of material processed using a new technology, and the net value of separating impurities from process residue can be calculated. Because of incentives to maintain the confidentiality of cost information, the heuristic model ‘was developed to allow generalized analysis of new technology without revealing sensitive information. Methods for using the model, listed below, may not generate detailed information, but may help establish a dialogue between representatives of the mining industry and technologists resulting in information useful in evaluations. One or more of these approaches may provide valuable information that helps the researcher and decision

bottom line responses that do not reveal details

Using the heuristic model as a basis for qualitative evaluation of the technology

Providing sufficient information to promote voluntary cooperation

Summary

This report points out opportunities for the mining industry to improve operations by responsible emission and by-product management and low-cost and efficient production. The dialogue between the mining industry, government, and the research community has

strengthened the potential to capture these opportunities and can help realize A

ORNL engineers developed simplified descriptions of copper, lead, and zinc processes that identify process residue with high concentrations of commodity metals. These descriptions serve as a starting point for. clarifying the economic benefit of research into methods to recover these metals, or by-products. By identifying highly beneficial opportunities for by- product recovery, research can result in development of technologies that contribute to a more profitable, safer, and environmentally benign mining industry.

This paper identifies process residues by commodity sector as

Opportunities for technology development that result in economical recovery of by-products in the mining industry can be clarified by evaluating data on the value of process residue before separating impurities, after separation, and the cost of separation. Evaluation of
