一概述金刚石系单元素矿物,它是自然界中极其稀有的矿物,它的硬度最大,一般具有完整的晶形,耐酸碱性很强,在自然界中不易起化学变化。它的用途极广,用于作切削工具的速度比合金切削工具快十多倍,另外还用于精密仪器制造业,国防工业,钻探工程等,因此在祖国社会主义建设中,是迫切需要的贵重工业原料。金刚石在砂矿中的分布极不均匀,其沉积规律随古老河床的沉积规律而定。砂矿床中之金刚石均为100%之单体分离。因此从砂矿中选取金刚石,可省掉昂贵之破碎和磨矿作业,此种自然条对于节约国家投资极其有利。
An overview of diamond-based elemental minerals, it is an extremely rare mineral in nature, its hardness is the largest, generally have a complete crystal form, strong acid and alkali resistance, in nature is not easy to play a chemical change. It is extremely versatile and is used for cutting tools more than ten times faster than alloy cutting tools. It is also used in precision instrumentation, defense industry, drilling engineering and so on, so it is urgently needed in the socialist construction of the motherland Valuable industrial raw materials. The distribution of diamond in the sand is very uneven, the deposition law with the deposition of ancient river bed rules. Sand deposits in the diamond are 100% of the monomer separation. Therefore, from the selection of diamond sand, you can save expensive crushing and grinding operations, such natural items for saving national investment is extremely beneficial.
