Galena, a lead sulfide (PbS), is heavy, brittle, and breaks into cubes. Sphalerite is a zinc sulfide (ZnS) mineral that is brownish, yellowish, or black. It ordinarily occurs with galena and is a major ore of zinc. The grindability test was then repeated using a test screen size 20% of that used in the first testget price
Galena, also called lead glance, is the natural mineral form of lead(II) sulfide (PbS). It is the most important ore of lead and an important source of silver. Galena is one of the most abundant and widely distributed sulfide minerals. It crystallizes in the cubic crystal system often showing octahedral forms.get price
Galena value: Some mines produce more revenue from the silver content of their galena than from the lead content. Assume that we have a mine that produces argentiferous galena with an average composition of 86% lead, 13% sulfur and just 1% silver (as shown in the diagram on the left).get price

The Bond Ball Mill Grindability test is designed to give a measure of the grinding characteristics of a material by finding the amount of size reduction resulting from a controlled energy input. Ball Mill Grindability of a material depends upon its hardness, structure, the manner in which it is fractured. The grindability is useful in evaluating power requirements for grinding.get price

Aug 13, 2008 After dissolving galena in HNO3, adding HCl will precipitate BOTH silver chloride and lead chloride. Thre lead chloride can be leached out by filtering the precipitate off and boiling it in water and discarding the solution. The remaining precipitate should be boiled a couple of times more, discarding the solution each time.get price
