为选矿目的而作的显微镜研究方法的主要内容,其中之一就是矿物晶体颗粒大小的测定和矿石单体分离程度的检查。关于矿石中矿物晶体颗粒大小,对选矿来说从来没有一个完整的定义,因为矿物颗粒的形状是非常不规则的。所以有必要讨论其表示方法及提出形状校正系数。而关于矿石单体分离度的问题也是这样,到目前为正,一般是由显微镜检查及选矿磨矿试验及篩分分析等考察,但没有理论上的总结及完整的表示方法。因此,想用数理统计法及封闭图形来讨论单体分离度问题。根据这些曲线及图形,而换算为磨矿的理论曲线和磨矿标准。当然这些试验都是极不成熟的,特别是形状校正系数,想在今后进行大量试验,从被测矿物的体积或重量并考虑各种矿石的物理性质及不同的破碎条件等来确定。希望各有关方面对此给予协助,并提出宝贵的意见和批评。
One of the major components of microscopic research methods for beneficiation purposes is the determination of the size of the mineral crystals and the degree of separation of the ores. With regard to mineral crystal grain size in ores, there has never been a complete definition of beneficiation because the shape of mineral grains is very irregular. Therefore, it is necessary to discuss its representation and propose the shape correction factor. The problem about the resolution of ore monomer is also true, up to now, generally by microscopic examination and dressing grinding test and screening analysis, etc., but there is no theoretical summary and complete representation. Therefore, want to use mathematical statistics and closed graphics to discuss the issue of monomer resolution. According to these curves and graphics, and converted to grinding the theoretical curve and grinding standards. Of course, these tests are extremely immature, especially the shape correction factor, want to carry out a large number of tests in the future, from the measured volume or weight of minerals and considering the physical properties of various ores and different crushing conditions to determine. We hope all relevant parties will help them and offer valuable opinions and criticisms.
