Introduction of Lead-zinc Ore Dressing Process. 1. Crushing and Screening. Two lead-zinc bulk flotation can discard tailings at once and reduce metal loss. Besides, the direction of crude concentrate and the return of middlings separation can achieve flexible configuration, which adapts to the change of ore grade.
【Introduction】 (CH3)2CHCH2CH(OH)CH3 【Characteristic】 Store in a cool, dry, ventilated warehouse 【Application】 Used as a good frother for lead-zinc, copper and molybdenum ore, copper and gold and non-metallic mineral. Strong selectivity and high activity. The foam it form is thin brittle and not sticky, without collecting and the use
If there are zinc, manganese and antimony, the floatability is weakened. The different impruties in galena cause the different effort of inhibitor. Cerussite is the major lead oxide. Generally after the vulcanization of Na2S, the flotation is carried out with advanced xanthate as collector. The suitable pH of vulcanization is about 9.5.
For a zinc extraction plant in Tibet, there are much slime in the raw ore. According to the zinc ore characteristics, Xinhai adopted pre-desliming, zinc sulfide flotation and zinc oxide flotation process. Finally, the production indexes were stable and the recovery rate of zinc
