the basics of gold mining and processing. placer deposits, such as streambeds where people can pan for gold, are not the typical locations used by commercial gold mining companies. the process begins when geologists take ore samples to determine the best places for companies to mine. once mining engineers know where gold is located and what other materials surround it, the mining process can begin. if the gold is located close to the surface, it’s mined with open-pit mining
gold and platinum. there are two methods: working with saltwater and working with acid. both work equally as well, but for a variety of reasons, including safety, cost and the kind of material that you are refining, you may choose to use one method over the other. there are two methods: chemical and electrolytic processes.
