Ores are left behind after mining certain varieties of stone.Ore can be smelted to create bars of pure metal or combined to create alloys.Many ores are quite valuable as mined without being refined, and a mason or stone crafter can work them the same as any stone. However, ores fall into the economic stone category, and so must be designated for non-restricted use in the z …

Processing. After mining, nickel ores are further processed to upgrade their nickel contents from 1-4% typical of the ores to concentrates with grades in the range 10-20%. Concentration involves crushing the ore and separating nickel-bearing from other minerals using various physical and chemical processing methods.

Laterite is both a soil and a rock type rich in iron and aluminium and is commonly considered to have formed in hot and wet tropical areas. Nearly all laterites are of rusty-red coloration, because of high iron oxide content. They develop by intensive and prolonged weathering of the underlying parent rock, usually when there are conditions of high temperatures and heavy rainfall with …
