美国Barrick资源公司有两座高压浸出厂,处理难处理的金矿石。由于矿石的矿物学原因,一座是碱法高压浸出,另一座是酸法高压浸出。操作的pH值对设备结构材料以及投资和操作费用均有明显的影响。下向扼要地重点介绍这些工厂的生产实践及经济状况。
Barrick Resources USA has two high-pressure leaching plants that deal with refractory gold ore. Due to the mineralogy of the ore, one is leaching by high pressure from alkali and the other is leaching by acid-based high pressure. The pH of the operation has a significant effect on the materials of the equipment and the investment and operating costs. Give a brief overview of the production practices and economic conditions in these factories.
