Canadian Metals Retains Electrochem to Test Langis Deposit

Canadian Metals Inc. is pleased to announce that it has retained the services of Electrochem Technologies & Materials Inc. to conduct a series of tests aimed at demonstrating the technical and economic feasibility of converting silica sand from the Langis deposit into various high value-added products for industrial applications.

The CTMP laboratory previously conducted grade improvement tests consisting of enrichment by physical means such as: (1) washing followed by desliming to remove fines and clays, (2) mechanical attrition to remove fines clay particles adhered to the surface of quartz grain and (3) wet high-intensity magnetic separation (WHIMS) of the grains. These tests succeeded in improving purity, but failed to achieve the specifications required to manufacture silica sand for the production of high added-value products required in certain industrial applications.

The Corporation is therefore turning to the know-how and industrial expertise of Electrochem Technologies & Materials to help meet these criteria, by defining:

• All possible ways of obtaining a silica sand or purified lump quartz required for the proposed industrial application
• Relatively simple operating procedures that use readily-available commercial reagents and have a lower operating cost (OPEX)
• A process that has a lower capital investment (CAPEX) and is therefore easy to set up
• A proposed method that is safe from an H&SE perspective and not environmentally restrictive, while minimizing the volume of waste.

Canadian Metals wishes to determine the best process for its silica sand quickly, and therefore aims to obtain evidence through a series of laboratory tests to be performed by Electrochem on samples from a multi-kilogram batch of concentrate obtained by enrichment during a previous program conducted at the CTMP laboratory.

In line with the above, Electrochem Technologies & Materials will therefore start an initial phase of work (Phase 1) aimed at demonstrating the applicability of a technology and its technical and economic feasibility.
