在全世界黄金生产中，斑岩铜矿和含金硫化矿是两种最主要的矿石资源。在冶炼、焙烧、湿法处理这些硫化矿之前，一般采用浮选领富集法进行处理。莱克菲尔德研究有限公司已经对许多大型矿床的矿石进行了研究，这些矿床有新发现的，也有正在开采的。研究的目的是通过采用新的流程设计和引进特殊的浮选药剂来提高金属回收率；还对麻岩铜矿矿床的变异性进行了研究，提出了多种选矿工艺。 In the world of gold production, porphyry copper deposits and gold sulphide ore are the two most important ore resources. In the smelting, roasting, wet processing of these sulfide ore, the general flotation collar enrichment method for processing. Research has been conducted on the minerals of many large deposits that have been newly discovered and are currently being mined. The purpose of the study was to improve metal recovery by designing and introducing special flotation reagents using a new process. The variability of the Maquonite deposit was also studied and various beneficiation processes were proposed.
