    Sulfide Ore Processing. our process allows us to contain the amount of sulfur that is released into our solution and capture it in our filter presses instead of releasing hazardous gasses into the earth’s atmosphere. Benefits of Partnering with TCB International.

  • Smelting and Roasting Ores to recover gold, silver and

    The two are actually different methods, but both involve heating the ore to high temperatures. Technically, any methods which consist of processing ore by heating it are called “pyrometallurgy”. The old timers took advantage of the chemical instability of sulfides by simply heating (or roasting) them to burn off the sulfur.

  • Sulfur Mining & Processing: What to Know General Kinematics

    The Sulfur Mining Process. From the late 1800s to the end of the 20th century, the Frasch process of sulfur mining was commonly used. This involved forcing super-heated water into a sulfur deposit so the sulfur would melt and come up to the surface by way of compressed air. During the latter part of the 20th century, mining or recovering sulfur
