    2016-1-8 · One free milling gold ore received for testing the application of the Mineral Jig in the Ball Mill Classifier circuit gave the following results: Head Ore, 0.65 oz. Gold per ton (Assayed) 0.643 oz. Gold per ton (Calculated) Amalgam from Amalgamation of Jig Concentrate: 0.471 oz. Gold from one ton head ore, or 73.3% of Gold from the original heads.Gold Recovery 101 Sepro Systems,2019-10-1 · In the case of low grade (< 1 g/t) free-milling gold deposits, the ore is often crushed and heap leached. While the recoveries are typically lower than what would be obtained with a conventional gravity-cyanidation flowsheet, the savings in CAPEX and grinding costs often justify this route. When clays or fine particles are present, the use of an agglomeration drum is necessary to prevent impenetrable
