Being free of sulfur, laterite nickel deposits do not cause a pollution problem as do the sulfide ores, but they do require substantial energy input, and their mining can have a detrimental effect on the environment (e.g., soil erosion). The range of process options is limited by the nature of the ore.
The mining methods differ with respect to the type of ore being mined. Since nickel is composed in two types of ores, both of them are mined differently. The sulfide ores are mined using underground mining methods though open-pit mining can also be done in early stages.

Jan 21, 2015· Pure nickel is a hard, silvery-white metal, which has properties that make it very desirable for combining with other metals to form mixtures called alloys. Some of the metals that nickel can be alloyed with are iron, copper, chromium, and zinc. These alloys are used in making metal coins and jewelry and in industry for making items such as valves and heat exchangers.
Environmental impacts of mining can occur at local, regional, and global scales through direct and indirect mining practices.
