Gold flotation. Flotation process is widely used for lode gold processing. In most cases, the flotation method has a good effect in sulfide-containing gold ore with high floatability. In addition, the flotation process is also used for polymetallic gold-bearing ores such as gold-copper, gold-lead, gold-copper-lead-zinc-sulfur ore.Web

Sulfur burns with a pale blue flame that may be difficult to see in daylight. Burning sulfur will flow and emits large quantities of sulfur dioxide (SO2), a toxic, irritating, and suffocating gas that can cause severe lung damage and death. Molten sulfur may evolve hydrogen sulfide (H2S) - H2S is a flammable gas and may present an explosion hazardWeb

The most important operations are roasting, smelting, and refining. Roasting, or heating in air without fusion, transforms sulfide ores into oxides, the sulfur escaping as sulfur dioxide, a gas. Smelting ( q.v.) is the process used in blast furnaces to reduce iron ores. Tin, copper, and lead ores are also smelted. Read More.Web
