Its cubic structure with perfect 90-degree cleavage planes along with its bright silver like metallic luster is eye catching. Most galena is mined as a lead ore. Argentiferous Galena is sought after for its silver content and greatly increases its ore value.These ore bodies generally trend north or northwest and dip approximately 70? west. Quartz veins, such as the Santa Maria and San Filipe veins carry ores of argentiferous galena and tetrahedrite. Zinc ore is composed mainly of smithsonite, a secondary zinc carbonate. Cerro Gordo ore bodies are localized by a combination of structural features. Buying Gold Bullion from JM Bullion.

When galena ore is smelted, it will produce 4 lead bars and 0-4 silver bars (with a 50% chance of each silver bar being produced). On average, each nugget of galena will produce approximately two bars of silver when smelted. Galena can also be used in alloy reactions requiring silver-bearing ore.Using the Bureau’s new process, galena concentrates are leached directly under oxidative conditions in waste fluosilicic acid at tem-. peratures less than 120°C. This solubilizes the lead and produces a residue containing elemental sulfur and other metal values.

One of the most widely distributed sulfide minerals, it occurs in many different types of deposits, often in metalliferous veins, as at Broken Hill, Australia; Coeur d’Alene, Idaho, U.S.; Clausthal Zellerfeld, Ger.; and Cornwall, Primary ore minerals in MVT deposits are generally galena (PbS) and sphalerite (ZnS). Fluorite (CaF 2 ) is common but has little economic value. Weathered or altered MVT ores may contain anglesite (PbSO4), cerussite (PbCO 3 ), smithsonite (ZnCO 3 ), hydrozincite (also a type of zinc carbonate), and secondary galena or sphalerite.In 1881, Robert Strahorn wrote “Wood river is the center of one of the most extensive belts of heavy galena ores in the world.” Another publication said the WRV’s silver belt was “one of the richest as well as one of the most extensive in the world…The Bullion belt and district is the richest yet discovered.” 15,000 people were expected by 1882.The surface deposits were Galena and digging down lead to Galena ore which I confirmed was what was being detected as hematite by the /oredistribution command with very restricted radius and y values.

There is a clear boundary between galena and gangue, and lead minerals and gangue monomers can be dissociated by crushing. Because the specific gravity of galena is relatively large, up to 7.4-7.6, while the specific gravity of gangue usually does not exceed 3.0, gravity separation can get a ...Galena is by far the greatest ore of lead. The extraction process to remove the lead from the sulfur is very simple, thus lead has been extracted from Galena since the earliest times. Galena from certain regions is rich in silver, and some specimens may contain as much as 20 percent silver. Because of this, silver-rich Galena is also an ore of ...Galena is a noticeably dense mineral, having a density of about 7.6 gm/cm 3. It has a metallic luster.
