sulfur production in 1991 from 17% in 1971 in the United States [1]. Mineral processing played only a small role in the elemental sulfur industry. When a sulfur ore was selected, a typical method was grinding the sulfur ore to about 28 mesh followed by froth flotation. Flotation concentrates were melted and filtered to produce sulfur products

Sulfur removal can be performed using two main methods: conventional pyrometallurgical (smelting/converting) and hydrometallurgical (flotation/leaching or bioleaching). Reduction of the sulfur content of iron ores is conventionally carried out by flotation after grinding (Weibai, 1983; Changxiang, 2001; Xingwang et al., 2009).

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.

Problem with gold recovery from sulphide ore: How may a mill get the maximum recovery of gold from a sulphide ore, at the least capital cost and at the same time obtain the highest net return.This latter point is most important. In many cases a gold mill using an all-cyanide flowsheet with fine grinding of all the ore will report very low gold content in the …

The elemental sulfur in the unground state may be mixed with the ore ahead of the grinding system thereby obtaining the desired fineness in grinding with the ore for the required reactivity. Sulfur dioxide may be stage added throughout the leaching system, or it may be added in a single step into the recycle liquor after filtration and before ...

Ignition tubes (75 mm x 10 mm test tubes) should be filled to no more than one quarter full with the iron–sulfur powder mix (see first step of the demonstration procedure). Using 0.2 g of the mixture is sufficient for the effect to be seen. Place a small plug of mineral wool in the mouth of each ignition tube.

a matte. Sulfur dioxide was emitted in this process and no attempt was made to capture it. There was only one exception, this being a process that was developed in Norway and which became known as the Orkla Process whereby elemental sulfur was produced. In this process, coke was charged together with the ore lumps to the furnace to reduce S02 to
