hello we provide concise yet detailed articles on "gold choices: process of mining gold" topic. the information here is sourced well and enriched with great visual photo and video illustrations. when you find the article helpful feel free to share it with your friends or colleagues.
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 its mined with openpit mining
gold is generally found in two types of deposits: lode vein or placer deposits; the mining technique used to extract the gold depends upon the type of deposit. once extracted the gold is refined with one of four main processes: floatation amalgamation cyanidation or carboninpulp.
term definition. process mining is a method of gathering enterprise data event logs and processing this data into a visual workflow for monitoring and analysis.. g oing through the tool that combines data mining and process analysis organizations can detect gaps and loops in corporate operations prioritize work towards efficiency define opportunities and make conclusions for further
for copper sulfide ore smelting is a stage in the process of pyrometallurgy in which a series of steps use heat and a chemical reducing agent to decompose the partially processed ore drive off other elements as gases or slag waste and leave just the concentrated copper base behind.
mining of copper ores is carried out using one of two methods. underground mining is achieved by sinking shafts to the appropriate levels and then driving horizontal tunnels called adits to reach the ore. underground mining is however relatively expensive and is generally limited to rich ores. el teniente in chile is the world's largest underground copper mine.

by 2000 bc the process of purifying goldsilver alloys with salt to remove the silver was developed. the mining of alluvial deposits and later lode or vein deposits required crushing prior to gold extraction and this consumed immense amounts of manpower.
process steps include mining concentration roasting smelting converting and finally fire and electrolytic refining. mining produces ores with less than 1 percent copper. concentration is accomplished at the mine sites by crushing grinding and flotation purification resulting in ore with 15 to 35 percent copper.

when gold is combined in this way it forms an alloy. scientists and goldsmiths often use colors to designate the various gold alloys that are possible. for example white gold is made by combining gold with nickel silver or palladium. red or pink gold is an alloy of gold and copper. and blue gold is the result of mixing gold with iron.
