皮马采矿公司为解决磨矿过程的变化已采用两种粒度分析仪样机,该分析仪可望最终用于磨矿回路的给矿自动调节,从而提高磨矿处理能力并能更均匀磨矿。皮马公司再扩建后的经济效果该公司原处理地下开采的少量高品位矿石,而现在在亚利桑那州新建一规模巨大的露天开采的低品位铜矿。自1957年选矿厂以3000吨/日规模处理含铜1.8％的高品位铜矿
Two particle size analyzer prototypes have been used by Pima to address changes in the grinding process, and the analyzer is expected to automatically adjust the feedstock eventually used in the grinding circuit to increase grinding capacity and allow more uniform grinding. The Economic Effect of the Further Expansion of the Pima Company The Company originally handled a small amount of high grade ore mined underground and now has a large open-pit low-grade copper mine in Arizona. Since 1957 concentrator to 3000 tons / day scale copper content of 1.8% of high-grade copper
