Abstract:

Haxiwa gold polymetallic deposit belongs to the tectonic altered rock type.Through analyzing the characteristics of process mineralogy，such as mineral chemical composition，mineral composition，structure，ore particle size and embedded relationship，we identified the mineral composition very complex.Overall，the results demonstrate that gold is the main recoverable minerals and argentite，anglesite，cerusite，galena and sphaleriteare the next recoverable minerals.Additionally，pyrite and arsenopyrite are primary carrier mineral of gold，the main mineral containing gold is electrum and main occurrence state of gold presents angular granular inclusion.The findings in the present work are helpful for making full use of valuable mineral and it can provide reliable process mineralogy basis for establishing economic and reasonable mineral processing technology in future.

Key words: Haxiwa gold polymetallic deposit, gold, occurrence state, valuable mineral, Qinghai Province
