本文阐述利用钻孔取样分析,来确定不同品位的矿体界线。并介绍用低台阶小电鍷进行采装可以严格控制品位和提高回收率。 Basic联合公司在内华达州的加布斯开采菱镁矿和水镁石已经有27年了。这是一个中型的露天矿。该菱镁矿矿床位于内华达州西北部的尼耶县,在隆宁以东大约48公里帕腊迪斯山脉的西坡上,海拔1500—1800米。菱镁矿和共生的水镁石主要用来制造炼钢
This article describes the use of drilling sampling analysis to determine the different grades of ore body boundaries. And introduce the use of low-level small electrical 采 for rigorous control of taste and improve the recovery rate. Basic Associates has been producing magnesite and brucite in Gabus, Nevada for 27 years. This is a medium-sized opencast mine. The magnesite deposit is located in Nye County, northwestern Nevada, on an elevation of 1,500-1800 meters on the western slope of the Paracels, about 48 km east of Longning. Magnesite and symbiotic brucite are mainly used to make steel
