Process Of Iron Ore Processing Plant. Screening: The first one is screening the iron ore to separate fine particles below the crusher's CSS before the crushing stage. Crushing and stockpiling: This step involves breaking up the iron ore to obtain an F80 grind size before it can be ground. Once the ore is crush, it is diverted to a stockpile and then fed into the mill

Comminution tests (ball mill grindability) returned average Bond Work Index (BWI) values that categorize MET-1 as medium and MET-2 as moderately soft. More testwork will be undertaken to improve the 24- to 48-hour gold recoveries and optimize the leach residence time. Improvements are expected with these tests.
