copper-molybdenum bodies that were emplaced during the youngest phase of batholith formation, the Bethsaida Phase. Mineral zonation is well developed at both deposits. In each, the copper-iron zones are concentric and comprise bornite at the centre, surrounded by a chalcopyrite zone, which in turn is enveloped by a pyrite zone.

Lumina Gold Announces Improved Flow | Lumina Gold Corp.

The study's conclusion is that flotation plus leaching is the preferred flow sheet given the enhanced recoveries versus the 2018 PEA (see September 23, 2019 news release). Whole ore leaching only produced doré and despite having higher gold recoveries, it does not receive the benefit of recovering copper, a substantial by-product.

Molybdenum Processing

Flotation separates the metallic minerals from the gangue this way and – in the case of copper/ molybdenum ores – separates molybdenite from copper sulphide. The resulting MoS 2 concentrate contains between 85% and 92% MoS 2. Further treatment by acid leaching can be used to dissolve impurities like copper and lead if necessary.
