Ore processing (or ore dressing) is the separation of iron ore from gangue in order to optimize the blast furnace process! In principle, the undesirable gangue can never be completely separated from the iron ores during ore dressing. This means that a certain amount of unwanted elements always enters the blast furnace process.

The process of extracting tin from tin ore varies according to the source of the ore deposit and the amount of impurities found in the ore. The tin deposits in Bolivia and England are located deep underground and require the use of tunnels to reach the ore. The ore in these deposits may contain about 0.8-1.0% tin by weight.
Mar 16, 2021· One welder started work at 13 after his dad was killed on the job. Workplace accidents were common. Black workers were often assigned positions in the so-called “coke ovens,” where coal is baked before it’s mixed with iron ore to make steel, “the hottest, most noxious work in the entire steelmaking process.”
Ore is natural rock that contains valuable minerals, typically metals and is extracted from the earth through mining and extracting the valuable metals or minerals. The grade of ore refers to the concentration of the valuable material it contains. Subsurface mining involves digging tunnels or shafts into the earth to reach buried ore deposits.
