Sommaire: Environmental desulphurization is an attractive alternative for the management of acid generating tailings. Sulphide bulk flotation is the most commonly used method to produce desulphurized tailings, as shown from many previous works. This process can reduce the volume of problematic tailings to manage by making a sulphide fraction concentrate. The desulphurized tailings can then be used as construction material for an engineered cover to prevent acid mine drainage.

Sommaire: Traditional planning of mines and scheduling of production is largely based upon the modelling of ore grade. It is known, however, that grade is not the only characteristic that can be taken into account to maximize performance at the processing plant and efficiency of tailings disposal. Ore processing plants respond well to feed that is consistent over time and that has known physico-chemical characteristics, which can be used to improve plant design and performance through the management of...

Sommaire: Over the last few years, a number of research projects to prove out the concept of applying fuel cell technology to underground mining vehicles have been managed by Vehicle Projects LLC for the Fuelcell Propulsion Institute. These have been carried out with the support of mining companies, trade unions, regulatory agencies, equipment manufacturers, research laboratories, technology developers, universities, and consultants.

Sommaire: The 20th century saw changes in the mining and metallurgical industry not only technically but also in social and environmental expectations. As projects become larger their visibility raises concerns among communities of interest, and mining companies must adopt a transparent and open approach to assure success. An equally important task is to anticipate the standards that will be required to meet expectations.

Sommaire: In 1997, a group of Canadian mining companies met to review the Mine Environment Neutral Drainage (MEND) program and to consider future activities. They concluded that Canadian industry and Natural Resources Canada (NRCan) should fund a small secretariat in Ottawa to support technology transfer in Canada, and that it was important for industry to continue the momentum of MEND on an international scale.
The need for the International Network for Acid Prevention (INAP) was strongly endorsed by...

Sommaire: The Las Cristinas deposit in Venezuela contains proven and probable reserves of 12.8 million ounces of gold at a grade of 1.20 g/t. The deposit comprises fully oxidized saprolite (SAPO) overlying a layer of sulphide-enriched saprolite (SAPS) which lies above carbonate- leached bedrock (CLB) and carbonate stable or un-leached bedrock (CSB). Gold occurs at a similar concentration in all lithological units.
Virtually all of the copper originally in SAPO has been leached out and deposited in the...
