Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy.The primary operations are comminution and concentration, but there are other important operationsget price
Head grade The average grade of ore fed into a mill. Heap leaching A process whereby valuable metals, usually gold and silver, are leached from a heap, or pad, of crushed ore by leaching solutions percolating down through the heap and collected from a sloping, impermeable liner below the pad.get price

Crushed ore is divided into various fractions by passing it over sieves through which undersized material falls. In this way, lump or rubble ore (7 to 25 millimetres in size) is separated from the fines (less than 7 millimetres). If the lump ore is of the appropriate quality, it can be charged to the blast furnace without any further processing.get price

The blast furnace is still the dominant form of iron production, but over the years, direct reduction methods have increased due to a number of reasons. Overall, iron production methods have optimal requirements with respect to the feed materials especially iron ore. In this study, tests were carried out on Muko iron ore from Uganda to analyse its suitability to meet the feed requirements ofget price
Physical Properties of Cassiterite. Cassiterite has several properties that aid in its identification and enable it to be found in minable quantities. Its adamantine luster, high hardness, light streak, and high specific gravity are helpful in its identification.
