为了保证分离浮选铅锌的良好浮选状态,从泡沫液面水平与氰化钠添加量之间的特定关系入手,根据泡沫面高低,利用计算机,对氰化钠的添加量进行反馈修正,从而实现了分离浮选的自动控制.氰化钠的单位耗量减少了6克/吨,每年节约药剂费用184.3万日元.改善了分选指标,提高了铅、锌回收率及铅精矿品位,从而增加了收益,每年增收1841.5万日元.大幅度地节省了浮选操作劳动力.
In order to ensure the good flotation state of lead and zinc in flotation separation, starting with the specific relationship between the level of foam liquid and the amount of sodium cyanide added, according to the height of foam surface, the amount of sodium cyanide added was corrected by feedback, So as to realize the automatic control of separation and flotation, the unit consumption of sodium cyanide is reduced by 6g / ton, and the annual cost of medicine saving is 1.8433 million yen, the sorting index is improved, the lead and zinc recovery rate and lead concentrate Grade, thereby increasing the revenue, an annual increase of 18.415 million yen. Significant savings in the flotation operation of the workforce.
