on extracting lithium from oil-field wastewaters. Although usually low-grade, this can be an additional resource base if the right technology is forthcoming. Direct lithium extraction For geothermal or oilfield brines to succeed as a source of lithium supply, a proven process for DLE will be required. There are a number of companies
The process of converting nickel ore into usable products begins with its extraction from the earth. Nickel ore is found in two primary forms: laterites and magmatic sulfide deposits. Laterites, which are encountered in tropical weathered soils, are predominantly composed of minerals such as garnierite and nickeliferous limonite.
