摘要
通过对矿石物质组分及其赋存状态研究,发现安徽铜陵新桥锰矿床的锰除主要赋存在菱锰矿中外,有约30%赋存在方解石和金属硫化物中,而且金属硫化物中含有大量金。认为方解石和金属硫化物中锰的大量存在是选矿过程中锰回收率低的主要原因;该矿床具有较高的金综合利用价值,对寻找金属硫化物富集带有重要的找矿意义。
Study on the ore compositions and their existence state indicates that the manganese element of the Xinqiao ore deposit exists mainly in dialogite and 30% in calcite and metallic sulphides that contain a great deal of gold. It is argued that existence of a lot of manganese in calcite and metal sulphides is the major cause of low recovery of manganese in the process of ore concentration. The deposit is thought to be of high comprehensive utilization value and important to prospecting metal sulphides-abundant belt.
