Tailingsfo What are tailings? Their nature and production

The Mining Process Waihi Gold

A slurry of ground ore, water and a weak cyanide solution is fed into large steel leach tanks where the gold and silver are dissolved. Following this leaching process the slurry passes through six adsorption tanks containing carbon granules which adsorb the gold and silver. This process removes 93% of the gold and 70% of the silver.

Because tailings have no financial gain for the producer, they are usually stored in the most cost effective way. There are several ways to store tailings following the production process, but the most common method is to pump the tailings slurry to a surface settling pond or impoundment.

Tailings? Eco General Discussions

Well, tailings do cause pollution because the process (milling) doesn't extract all of the metals from the ore, leaving some behind in a form of dust particulates or a liquid slurry, which is has small enough metal particles to seep into water supplies when it rains, or blown through the air during windy days.

Mining Water for all

Mining produces mainly tailings (the waste materials left after the valuable ore is separated out) and overburden (the waste materials removed to reach the ore). During the mining process, water within and around the mine is usually contaminated, so treating the mine water before it is discharged back into the environment is a major issue [2].
