Sustainable development - From by-product synergy to capital stock turnover

Sustainable development in the mining and metallurgical industrial sectors can be implemented by two distinct groups: the managers and operators of existing facilities, working with industrial processes and systems that have been operating for many years, in some cases, several decades; and those who are engineering and building new facilities or upgrades of existing plants. The focus of this paper is to look at approaches and tools available to bring sustainable development thinking and action to these two distinct areas. The paper will discuss the concept of working with existing facilities and processes to minimize waste and maximize product from a regional raw material/resource consumption perspective using by-product synergy. The BPS concept has been carried out in Texas (e.g., TXI-Chaparral’s STAR), in Calgary, Alberta, with Suncor assistance, in Montreal, Quebec, with Noranda as project leader, and currently in Ontario with Dofasco as industry champion. Successful outcomes are presented. The paper will also discuss a new approach to designing greenfield facilities or upgrades to existing plants using a sustainable development review process. Undertaking the review early in every project can institutionalize the concept of discussing and implementing waste elimination, design for environment, eco-efficiency, risk minimization and community awareness and involvement in the future capital stock. The review process has been developed as an excellent tool for measuring and reporting on a corporation’s sustainable development progress. Examples of how this approach has been adopted in the mining and metallurgical industry, and the resultant outcomes are given.

Summary: A modular gold processing unit (MGPU) was designed, installed and operated over an eight-month period by RSW-Béroma at the Granada mine located near Rouyn-Noranda, Quebec. A description of the project geology, plant set up, as well as exploitation results, including productivity and profitability curves, are given for a small-scale mining operation in comparison with larger ones.

Summary: The application of biologically assisted methods for metal extraction in the mining industry has a long history, but development of modern techniques has been relatively slow. There is, however, a resurgence of interest in the industry with the recent development of methods to successfully treat base metals concentrates. Two major pilot plant programs for treatment of chalcopyrite concentrates have been initiated in the past year and results from one are beginning to be released. This paper...

Summary: Competitive pressures dictate that the mining industry moves to larger mobile underground haulage equipment with more advanced equipment mechanization, higher levels of autonomous operation of machines, and longer periods between access by maintenance personnel. Since such new machines will of necessity be more complex than existing designs, machine reliability has become a key issue in progressing toward advanced mobile underground haulage equipment. Reliability and maintainability models of...

Summary: This paper reviews the Falconbridge-SMRQ’s Raglan project in northern Quebec and the process that was used in developing its current long-term mine plan. Challenges were many and not only limited to the longevity of the project, numerous ore deposits (both underground and open pit), and a 40 km property strike length. As a result of its remote northern location, other factors such as progressive reclamation, leachable mine waste, water treatment, and waste management were also part of the...
