smelting: Metal extraction process in which an ore (usually mixed with purifying and/or heat generating substances such as limestone and coke) is heated at high temperature in an enclosed furnace. After a reducing reaction (see reduction), lighter orecomponents (impurities called slag or tailing) rise to the top and float on the molten metal. ...

Extraction of copper from copper sulfide minerals by roasting and smelting, a tutorial suitable for chemistry students ... The earliest evidence of copper smelting occurs in Serbian artefacts dating from around 5000 BC. ... Mining produce ores containing 2% or less of copper.
Roasting takes the place of fine crushing, as the ore from the roasting furnace is either found somewhat spongy in texture or the grains of silica in which fine gold may be incased are split or flawed by the fire. For quicksilver amalgamation very fine crushing is necessary to bring all gold particles in contact with it.

Bruckner roasting furnaces were builtwhich, alone, doubled the roasting capacity of the area to 1000 tons per day. By December 1887 the Butte mines surpassed those of Lake Superior and became the number one copper source in the country. By the end of the 19th century, The Butte copper mines became the largest copper producers in the world.
Roasting is a process of heating of sulfide ore to a high temperature in presence of air. It is a step of the processing of certain ores. More specifically, roasting is a metallurgical process involving gas–solid reactions at elevated temperatures with the goal of purifying the metal component(s).
In celebrating cooks at mining canteens, I also seek to describe a job in mining that most do not write about. If you like cooking, then maybe a job at a mine canteen is for you.

Sphalarite accumulates in deposits that can extend far underground. For this reason, underground mining is the method of choice to retrieve it. Other mining methods, like surface mining, would be far too expensive and difficult. One way to determine that underground excavation is more beneficial is by calculating what is known as the strip ratio.
Salt is generally produced one of three ways: deepshaft mining, solution mining or solar evaporation. Deepshaft mining is much like mining for any other mineral. Typically, the salt exists as deposits in ancient underground seabeds, which became buried through tectonic changes over thousands of years.
Roasting the ore 5 The lead concentrate fresh from the filter needs to be further refined to remove the sulfur. After the concentrate is unloaded at what is called the sinter plant, it is mixed with other leadbearing materials and with sand and limestone. Then the mixture is spread on a moving grate.
