How to Process Tailings Water of Lead-zinc Ore? - Xinhai

There are a variety of toxic heavy metal ions in lead-zinc tailings, these ions often exists in tailings as solid form, but with the change of physicochemical properties, the internal toxic ions in tailings will dissolve, which is not good for the recycling of lead-zinc tailings water. Here are several common methods to process lead-zinc tailings water.

20.1 Metal Deposits – Physical Geology - opentextbc.ca

When ore is processed (typically very close to the mine), it is ground to a fine powder and the ore minerals are physically separated from the rest of the rock to make a concentrate. At a molybdenum mine, for example, this concentrate may be almost pure molybdenite (MoS 2). The rest of the rock is known as tailings. It comes out of the ...

Gold Tailings: Hazards and Opportunities | INN

Tailings from gold mining operations can pose a threat to the environment and health of nearby communities. Not only can this waste be harmful if it leaches into groundwater, but it can also mean losing minerals still contained in the residue. One of the largest hazards often found in abandoned gold mining tailings is acid mine drainage.
