galena processing sulfite

Galena - an overview | ScienceDirect Topics

Galena, a lead sulfide (PbS), is heavy, brittle, and breaks into cubes. Sphalerite is a zinc sulfide (ZnS) mineral that is brownish, yellowish, or black. It ordinarily occurs with galena and is a major ore of zinc. The iron sulfide pyrite (FeS), which is also called fool's gold, is …

Galena - Wikipedia

Galena, also called lead glance, is the natural mineral form of lead(II) sulfide (PbS). It is the most important ore of lead and an important source of silver.. Galena is one of the most abundant and widely distributed sulfide minerals.It crystallizes in the cubic crystal system often showing octahedral forms. It is often associated with the minerals sphalerite, calcite and fluorite

Sodium Sulfites - an overview | ScienceDirect Topics

The Wellman-Lord process uses sodium sulfite to absorb SO 2, which is then regenerated to release a concentrated stream of SO 2. Most of the sodium sulfite is converted to sodium bisulfite by reaction with SO 2, as in the dual alkali process. Some of the sodium sulfite is oxidized to sodium sulfate.

Fire Assay Procedure - Mineral Processing & Metallurgy

Fire assay procedures uses a combination of intense heat (1900 °F) that is produced by a furnace, dry reagents called fluxes, and bone ash containers called crucibles and cupels. One uses this combination to fuse the fluxing agents and to isolate the precious metals. The ability to fire assay a substance relies on a number of facts.

Contains 86.6% lead, more or less silver, up to 1% or more, sometimes as a part of the galena, but sometimes as another mineral (as argentite) mixed with the galena. The opinion that paying quantities of silver are found oftener in fine-grained than in coarse-grained galena is not well founded.

Lead Smelting - Base Metal Smelting

The process in which galena is smelted requires two important chemical reactions to occur within the furnace. 1) The galena is roasted (reacts with O2) in order to remove the sulfur component of the metal sulfide [2]. Roasting is a method where a sulfide ore (i.e an ore containing PbS) is heated in air which converts the metal sulfide to either ...

Rcovery of gold in pyritic ores - Mine Engineer.Com

The pyrite in which small amounts of gold occurs is of crystalline variety (primary pyrite). The characteristics of primary pyrite are a absence of porosity, an extreme brittleness, a resistance to oxidation, and the existence of gold possessing a weak susceptibility to magnetism (due to a fine coating of a iron compound).

Lead smelting - Wikipedia

Galena, the most common mineral of lead, is primarily lead sulfide (PbS).The sulfide is oxidized to a sulfite (PbSO 3) which thermally decomposes into lead oxide and sulfur dioxide gas.(PbO and SO 2) The sulfur dioxide (like the carbon dioxide in the example above) is expelled, and the lead oxide is reduced. Anglesite, Cerussite, Pyromorphite, Mimetite and Wulfenite are other lead ores.
