Geological Feature of the Huangjiawan Ni-Mo Deposit in Zunyi of Guizhou and its Prospect for Development

Abstract

The recent reconnaissance shows that the Huangjiawan Ni-Mo deposit is large inits site and worthy of further exploration and study for its development. The deposit occurs as a continuous lenticular sheet 0. 05-0. 5 m thick on average, maximum of 2m, and contains 10 % -15 % ofNi + Mo. The dominant minerals of economic importance are non-crystalline Ni-Mo sulfides associatedwith Zn, Cu, Se, and some precious metals of Au, Pt and Ir. Field observations indicate the deposithad a sedimentary origin. In the author's opinion, a wet preoxidation processing of ores is perhapsapplicable to producing this new kind of dePOSit to protect environment and to obtain a better profit.
