The project to be undertaken will aid in the replacement of a conventional practice of pyrometallurgical treatment of a semi-waste product (converter slag) Converter slags contain up to ~3% of No, Co and CU, and are generated in large quantities making it uneconomical to leave the metals unrecovered. The conventional technology for metal recovery results […]

    Crosshole tomography using seismic waves is a  useful technique for the mapping of ore containing sulfides between drill holes. The technique uses sound waves generated in one drill hole, and received in a second drillhole. Images are then formed in a manner analogous to medical tomography. However, conventional crosshole tomography does have limitations […]

  Discarded unattended waste slag soon becomes acidic resulting in an uncontrolled source, thereby releasing metals to the environment by a process known as Acid Mine Drainage (AMD). Traditional Pyrometallurgical methods to extract base metals from ore tailings have focused on using acid that is produced locally as a result of smelting operations, and Oxygen […]

The proposed study is a part of a project that will aid in implementing an environmentally clean technology for the recovery of Ni, Co and Cu from slags (waste and semi-waste materials) of nickel production in Ontario. The conventional technology for metal recovery can treat only slags with a high content of valuable metals (~3%), […]

Underground miners traditionally work in harsh environments containing dust and noxious gases. Recently, there is concern that the increasing risk of heat exposure may compound the deleterious effects of these conditions and further subject the workers to increased risk of heat stress. A new and growing challenge to the industry is that the Ontario mining […]
