Question

Write down the sources of classification of mining waste and radioactive waste ?!

--->Do not spam !! ​

Answer 1

Answer:

RADIOACTIVE WASTE

• Radioactive (or nuclear) waste is a byproduct from nuclear reactors, fuel processing plants, hospitals and research facilities.
• Radioactive waste is also generated while decommissioning and dismantling nuclear reactors and other nuclear facilities.
• There are two broad classifications: high-level or low-level waste.

MINING WASTE

• Waste occurs in several stages of the mining process and throughout the life of the mine, from the first exploration drilling project to the last processed material before mine closure.
• Several types of waste are generated in a mine, but three types stand out with the largest volume: waste rock, tailings and mine water.
• In some cases, the mine uses certain chemicals such as cyanide in the processing stage.
• These chemicals often account for a small volume of the total waste, but can pose a large risk due to their high toxicity.

Answer 2

Mining wastes include waste generated during the extraction, beneficiation, and processing of minerals . Mineral processing operations generally follow beneficiation and include techniques that often change the chemical composition the physical structure of the ore or mineral .

Radioactive (or nuclear) waste is a byproduct from nuclear reactors , fuel processing plants , hospitals and research facilities . Radioactive waste is also generated while decommissioning and dismantling nuclear reactors and other nuclear facilities .
