The established lead-zinc ore flotation processing scheme is to add zinc sulphate (ZnSO4) to the grind to control metal ion activation (sphalerite depression). Often metabisulphide or other sulphidation chemicals are added with the zinc sulphate for iron sulphide mineral depression.

16.08.2022Lead ore is a somewhat uncommon ore that yields lead and small amounts of silver. Obtaining Lead ore is less common than iron ore, but more common than gold ore. It occurs at relatively low levels in the world (layers 15-35). Lead ore veins are slightly smaller than iron ore veins, and may contain one or two blocks of silver ore as well.
