IMA Bulk Ore Sorting System (BOSS) technology is the most economic option for pre-concentration for your mine. IMA BOSS typically sorts ore and waste rock and/or different grades of ore by analyzing the mill feed on the primary crushed ore conveyor in short-time batches. No ore screening or other pretreatment is required. To proceed with the BOSS concept a simple application study is performed with your samples at IMA BOSS Laboratory. This lab study is then followed by a short pilot test in the mine with an FCA unit mounted over on the mine’s existing ore conveyor. This combination of IMA BOSS lab and field studies, together with economic benefit calculation shows in a few months bulk ore sorting’s potential and proposed sorting arrangement for mines.
