mining sodium sulphate in Saskatchewan

Sodium sulphate remains when the water is removed. One method of obtaining the salt is to pump the water into smaller ponds and allow it to evaporate. Then the crystals can be gathered. The harvested salt is piled near the plant. After the salt is processed in the plant the dried sodium sulphate is stored. The product is transported to customers by truck and by rail.

Acid mine drainage - Wikipedia

Acid mine drainage, acid and metalliferous drainage (AMD), or acid rock drainage (ARD) is the outflow of acidic water from metal mines or coal mines.. Acid rock drainage occurs naturally within some environments as part of the rock weathering process but is exacerbated by large-scale earth disturbances characteristic of mining and other large construction activities, usually within rocks

Heap leaching - Wikipedia

Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and re-separate them after their division from other earth materials. Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the
