钼精矿的脱水干燥过程是整个选矿流程的重要组成部分,它的好坏不仅直接关系到产品能否达到国家标准出售的问题,而且关系到经济效益高低的问题。钼精矿产品标准不仅对产品中钼的含量和杂质含量有严格的要求,而且对油水分的含量也有严格的要求。钼精矿价格表中规定:如钼精矿含水(包括油汁在内)大于4%时,每增加1%,每吨减价50元。由于脱水干燥过程常常难以把精矿油水分控制在国标之内,我公司目前仍按6%以下出厂销售。因此,82年销售精矿中有275批含油水分量超标,共减价180700元;83年销售精矿中有253批含
The process of dehydration and drying of molybdenum concentrate is an important part of the beneficiation process. Whether it is good or bad is not only directly related to whether the product can meet the requirements of the national standard, but also relates to the problem of economic benefits. Molybdenum concentrate product standards not only have strict requirements on the molybdenum content and impurity content in products, but also have strict requirements on the content of oil and moisture. Molybdenum concentrate price list provides: If molybdenum concentrate water (including oil), including more than 4%, for every additional 1%, 50 yuan per ton reduction. Due to dehydration and drying process is often difficult to control the concentration of concentrate oil within the national standard, our company is still below 6% factory sales. As a result, there were 275 batches of oil-in-water in the 82-year sales concentrate that were over-priced, totaling 180,700 yuan; 253 batches of concentrate sold in 83 years
