贺县选矿厂主要生产锌精矿、锡精矿,综合回收铅和其它有用元素。入选矿石以外购为主,矿石性质多变、复杂,难选程度大。为了提高的经济效益,选矿厂着重对其中高砷铁闪锌矿、高硫锡矿难选矿石进行了研究,小型试验与工业试验均获得较理想的结果,目前正在生产中应用。 (一) 矿石性质原矿多元素分析为(％):
He County concentrator mainly produces zinc concentrate, tin concentrate, lead and other comprehensive recovery of useful elements. Selected ore purchased outside, the nature of the ore is variable, complex, difficult to choose a large extent. In order to improve economic efficiency, the concentrator focuses on the high arsenic sphalerite, high-sulfur tin ore refractory ore were studied, small-scale experiments and industrial tests have been more satisfactory results are currently being applied in production. (A) the nature of ores ore multi-element analysis (%):
