| Ore Potential Analysis and Rapid Prospecting and Exploration Methods for Laterite Weathering Crust of Ultrabasic Rocks |
| The lateritic nickel deposit is the product of the weathering of ultrabasic rocks. In the ore body, there exist relict accessory minerals of the original ultrabasic rocks, such as chromite, titanochromite, vanadic ilmenite, and ilmenite, whereas weathering has formed minerals like hematite, limonite, nickel silicate, Co-bearing lithiophorite, and potash psilomelane. All these minerals have caused the ores to become vary characteristic “ natural alloy ores” with abundant Fe, Cr, Ni, Co and V. In addition, as the ore deposits are characterized by large size, shallow burial and easy exploration and opencasting, they have been gradually explored and utilized in large scale and have become the important exploitation objects for nickel materials. Exemplified by nickel deposits in Konawe area of Indonesia, this paper has tentatively made an analysis and summarization of the formation mechanism and prospecting methods for this kind of ore deposits. |
