- October 25, 2006 - CNSC Announces Decision on Proposed Ferric Sulphate Production at McClean Lake Project
Project Description
The McClean Lake Operation is a licensed mine and mill located in northern Saskatchewan. Ferric sulphate is used in the mill to remove dissolved arsenic in the tailings’ pore water prior to discharge to the Tailings Management Facility, and in the treatment of effluent prior to discharge from water treatment plants. It is expected that the demand for ferric sulphate at the McClean Lake Operation will increase significantly as new ores (e.g. from Cigar Lake, Sue E, Sue A) are processed.
COGEMA Resources Inc. has proposed to produce liquid ferric sulphate at McClean Lake from iron ore imported to site, which would replace the current practice of purchasing ferric sulphate commercially and transporting it to the mine site.
Before the Commission makes its decision on the proposal, an environmental assessment must be completed in compliance with the Canadian Environmental Assessment Act. The purpose of an environmental assessment is to identify the possible environmental effects of a proposed project, and to determine whether these effects can be mitigated before the project is allowed to proceed.
