Chemical explosions are more frequent than nuclear or physical explosions. Although chemical explosions are usually deliberate, they may also occur accidentally. Large physical explosions are relatively rare and usually accidental. Nuclear Explosions Nuclear explosions may be caused by either fusion or fission reactions. In a fusion reaction, the nuclei of two small atoms combine to form a ...

Toxic chemicals used to extract the valuable materials from the ore, such as the cyanide used in gold mining, remain in the tailings at the end of the process, and may leach out into ground water. Rock may naturally contain dangerous chemicals, such as arsenic and mercury, which leach into water much more readily after rock has been ground up and exposed to the wind and the rain. Get Price ...

When these three chemicals are ignited, a chemical reaction takes place very quickly. The products of that reaction are carbon dioxide, carbon monoxide, sulfur dioxide, and nitric oxide (all gases) as well as potassium carbonate and potassium sulfide (two solids). The four gases formed in the reaction are heated to very high temperatures and expand very rapidly. They form shock waves that have ...

· Explosives are used in the mining of many metals but not usually in mining coal. The material being sought as well as the material that is considered waste determines the chemical reactions being used at the mine to process the ore. I guess I am trying to say that you have posed an open ended question that could take years to answer.

Part of an interactive online booklet about copper mining explaining the electrolysis. page 5: Electrolysis : The blister copper is already virtually pure (in excess of 99% copper). But for today''s market, this is not really pure enough! It is purified further using electrolysis. This is known as electrolytic refining. The blister copper is cast into large slabs which will be used as the ...

Hydrochloric acid is consumed in many mining operations for ore treatment, extraction, separation, purification, and water treatment. Significant quantities are used in the recovery of molybdenum and gold. Hydrochloric acid is used to convert highgrade scheelite concentrate (CaWO4) and crude sodium tungstate to tungstic acid, which in turn, can be used to produce tungsten metal and chemicals ...

Nuclear explosives. Research during World War II (1939–45) produced an entirely new kind of explosive: nuclear explosives. Nuclear explosives produce their explosive power not by chemical reactions, as with traditional explosives, but through nuclear reactions. In some types of nuclear reactions, large atomic nuclei are split (or fissioned ...

Despite this early production, most copper used in the United States was imported from Chile until 1844, when mining of large deposits of highgrade copper ore around Lake Superior began. The development of more efficient processing techniques in the late1800s allowed the mining of lowergrade copper ores from huge openpit mines in the western United States. Today, the United States and ...

Conversely hand warmer packs use an exothermic reaction between chemicals that mix on activating the pack. One of the most important endothermic reactions, for which most of animal life depends is photosynthesis. The energy from sunlight is absorbed as water and carbon dioxide are converted to glucose and oxygen. 6H 2 O + 6CO 2 + sunlight energy ==> C 6 H 12 O 6 + 6O 2; See GCSE biology .

Laser and archeating are used in laser detonators, explodingbridgewire detonators, and exploding foil initiators, where a shock wave and then detonation in conventional chemical explosive material is created by laser or electricarc heating. Laser and electric energy are not currently used in practice to generate most of the required energy, but only to initiate reactions.
