一、實行混合浮选的意义我厂在1953年按苏联专家建议,将优先浮选法改为混合浮选法。在苏联专家的亲自指导下,经过半年多的小型浮选试验和一个多月的工业生产试验,混合浮选终于获得了成功。经过几年来的不断改进,混合浮选逐步的得到巩固和提高。实行混合浮选后,铅实收率提高了5.4％,锌实收率提高了0.3％,铅、锌产品质量都达到了一级品标准。无论在实收率方面和产品质量方面都超过了优先浮选的最高成绩,并且还节省了40.6％的浮选设备,和35％的浮选动力,为国家创造了巨大的财富。混合浮选的作业条件(一)铅锌全浮选阶段这一险段的浮选过程主要是提高混合实收率,并且也要达到铅锌产品所要求的混合精矿品位(铅20％、锌35％左右),不然混合精矿品位达不到,铅锌分离是无法完成精矿品位的。所以须根据矿石性质添加适
First, the significance of the implementation of mixed flotation I plant in 1953 by the Soviet Union experts suggested that the priority flotation law to mixed flotation law. Under the guidance of Soviet experts, after more than six months of small flotation tests and more than one month of industrial production tests, mixed flotation finally achieved success. After several years of continuous improvement, the hybrid flotation has gradually been consolidated and improved. After the implementation of mixed flotation, lead yield increased by 5.4%, zinc yield increased by 0.3%, lead, zinc product quality have reached a first-class product standards. Both in terms of yield and product quality exceeded the highest flotation priority, and also saved 40.6% of the flotation equipment, and 35% of the flotation power for the country has created tremendous wealth. Mixed flotation operating conditions (a) lead and zinc full flotation stage This section of the flotation process is mainly to improve the mixed real yield, and also to achieve the required lead-zinc concentrate concentrate grade (20% lead, Zinc 35% or so), or mixed concentrate grade, lead and zinc separation is unable to complete the concentrate grade. Therefore, according to the nature of ore added suitable
