Galena Wikipedia

Galena is the main ore of lead, used since ancient times.Because of its somewhat low melting point, it was easy to liberate by smelting.It typically forms in low-temperature sedimentary deposits. In some deposits the galena contains about 1–2% silver, a byproduct that far outweighs the main lead ore in revenue.In these deposits significant amounts of silver occur as included silver sulfide

Study on the Interaction between Galena and Sphalerite

Jul 31, 2019· 1. Introduction. Galena (PbS) and sphalerite (ZnS) are abundant in the earth and usually exist together in the same deposit. 1−3 Most lead–zinc ores are processed by differential flotation, in which galena is recovered first followed by sphalerite. 4,5 The addition/presence of lead ions (Pb 2+) in ore pulp can directly promote the sphalerite flotation. 6−8 Lead ions were considered to be

The influence of galvanic interaction on the dissolution

The oxidation and dissolution of galena should be accelerated, resulted in the formation of lead ions, lead-oxysulfide or lead-hydroxide, depending on the solution environment. Those oxidation products could remain in situ or migrate and adsorb on the pyrite and galena surface ( Sui et al., 1995 ).

Galena: Mineral information, data and localities.

Galena Group. Galena is the primary ore mineral of lead. Worked for its lead content as early as 3000 BC, it is found in ore veins with sphalerite, pyrite, chalcopyrite, tennantite-tetrahedrite, etc. and in skarns, as well as in sedimentary rocks where it may replace carbonate beds or be deposited in pore spaces.

Lead University of Denver

The only ore of lead that need be considered is galena. The problem of winning lead is complicated by the low concentration of lead in the available ore, sometimes only a few percent, and by the presence of numerous impurities. To make the process clearer, we'll assume we have relatively pure galena, and not many impurities. First of all

Galena Galena is the major ore of lead, and has been mined and worked since ancient times, e.g. the Romans used lead for weights, coins, vases, plumbing. Galena, a sulphide mineral, contains up to 86% lead, and may contain up to 1% silver. The large volume of galena that is processed for lead produces enough silver as a by-product to also make galena the leading ore of silver.
