莱州新城蚀变岩型金矿—145米中段选矿工艺矿物学研究

STUDY ON THE TECHNOLOGICAL MINERALOGY OF THE ORES FROM THE—145 LEVEL GOLD DEPOSIT OF ALTERED—ROCK TYPE IN XINCHENG, LAIZHOU CITY

摘要:

本文论述了新城金矿—145米中段金的选矿工艺矿物学特征。通过大量统计工作,查明了金的赋存状态,金矿物的成色、粒度、形态及嵌连关系等。采用物相分析了解金的解离情况,最后对影响金回收率的因素进行了分析,指出由于该区金矿物粒度细小,嵌连关系复杂,需提高磨矿细度才能提高金的回收率。

Abstract:

In this paper, the author discusses the mineralogical Characteristics in terms of ore-dressiffg technology for the gold ores in the-145 level of the Xincheng gold deposit in Laozhou. A great amount of statistic work has revealed the mode of occurrence of the gold, its fineness, grain-size, forms and contact rel ationship with other minerals. Phase analysis was employed to determine the possibility of liberation of gold minerals. Finally, the author analyses the factors that would affect the recovery of gold...
