Exploration: Like all metals, gold is primarily found in the earth waiting to be mined. This also means that the metal has to be worth mining, because you can't just dig a hole and leave it behind when you're done. To start mining for gold, the most common way to find it is by prospecting. Prospecting is primarily carried out using a range of different metal detectors. These metal detectors constitute a scientific and technological advance in the search for gold. They give accurate readings and indicate where the gold is based on the average depth of the ore. The advance is that it is much less arduous work than using a frying pan as our ancestors did during the Australian gold rush and many people find gold from fools (copper) and think it's gold. The gold we are looking for dates from the Archaean period (3.5 billion years ago) and, due to its rarity, is very valuable. Mining: Before all these mines are created, the company must create a living environment for people and families. , without them, many workers would not even attempt to work in the mine. Some requirements are fundamental; everyone must have housing, a sustainable food supply that must meet the dietary standards of not only the workers but also all other workers present, a water supply for obvious reasons, and recreational activities when the workers have a break and need to do something instead of standing there. Science has a major role in the creation phase of a mining community because it must all be profitable and mutually agreed with all other landowners, whether they own the land or belong to a specific ethnic group, without this agreement, no mine can operate. Before. Once the mine is finished you can't have an open hole in the ground either, environmental experts need to investigate...... middle of paper ...... highest purity of gold but carries a risk of harm to workers. He shares the scientific use of an electrolytic process. Gold is used as the cathode and hydrochloric acid is the electrolyte. This is where the danger and risk comes in: hydrochloric acid is a corrosive substance that eats away at human tissue and can potentially damage respiratory organs. Workers must therefore be fully equipped for their own safety. The gold is dissolved at the anode and the pure gold travels through the acid by ion transfer, the non-pure gold is then plated onto the cathode. Other metals likely to be present are silver, copper and platinum. At this point they can all be easily removed. This process is used on a very large industrial scale and has a significant set-up cost due to the quantity of gold which must be permanently dissolved in the electrolyte...
