In technology, four process schemes, such as crude ore cyanide leaching, flotation -cyanide leaching of flotation concentrate, fractional bulk flotation and selective flotation, were put forward.
技术上提出了原矿直接氰化浸出、原矿浮选—浮选精矿氰化浸出、原矿分步混合浮选和优先浮选四个方案,并比较了它们的特点。
Experimental results showed that applying selective flotation process and optimum reagent condition can efficiently separate the lead-zinc minerals and obtain lead concentrate of 63.
试验结果表明:采用铅优先浮选工艺和合理的药剂条件,可以有效地实现铅锌分离,获得铅精矿品位63。
Designing on this scale was not easy, so Zimmer says they had to be selective about what areas to concentrate on.
