Lateritic nickel ore deposits are surficial, weathered rinds formed on ultramafic rocks. They account for 73% of the continental world nickel resources and will be in the future the dominant source for the mining Heap leaching Wikipedia,Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and re-separate them after their division from other earth materials.

underground methods. Nickel-Cobalt Laterites Preamble Nickel-cobalt lateritic deposits are residual concentrations formed by tropical-style weathering of ultramafic rocks. Lateritic deposits include a number of deposit sub-types that result from different geological, geomorphological and climatic conditions. Typically, a profile is developed with different zones. Each zone exhibits differentMercury-free gold mining technologies: ,In the case of milling weathering (softer) ores, hammer mills are very durable and an appropriate method for small-scale gold mining. However, even working with lateritic and saprolitic ores, miners do excavate eroded layers of quartz–gold-veins which have a high Bond Index (i.e. are very hard).
