Tailings are the waste material from the ore processing phase, and often contain toxins left over from the ore separating process along with small amounts of heavy metals that were not fully removed. Lead is almost always contained in sulfide ores as galena, or lead sulfide 45. Waste rock material from mines that contain metal sulfides can lead ...
Your galena would need to be the sole mineral in your 'ore' I think. You likely can only answer all those questions be laboratory testing. Do you need to recovery your galena coarse to use it instead of ferrosilicon in a heavy media separation (sink/float) plant? If your galena is coarse grained, it will still jump out of a flotation cell.
Lead ore can be lead sulfide ore and lead oxide ore with the different distribution in the ore. Lead sulfide ore is commonly known as galena, which is mostly in the state of coarse grained disseminated in lead ore. While the lead oxide ores are mostly exist in fine condition. So they need different lead jigging plant to process.
