In southeast Kansas, where mining activities ceased in the middle half of the twentieth century, heavy metals in residue materials have created surface contamination problems. The erosion losses of chat material, a by-product of mining activities, have elevated levels of cadmium, lead, and zinc in nearby farmland to phytotoxic levels for the crops normally planted. Selective vegetation is being...

Large stratiform, syngenetic deposits commonly yield galena-lead isotope 'model' ages that agree closely with the stratigraphic ages of their host rocks. However, analyses in Table 1 from stratiform,shale-hosted deposits (located on Fig. 701 of Cambrian to Devono-Mississippian age in or adjacent to the Selwyn Bar,in in British Columbia and Yukon Territory do not give reasonable ages if the mode...

The Kangjiawan deposit, in the Shuikoushan district, Hunan Province, China, is a representative hydrothermal Pb–Zn–Ag– Au deposit in this region. The orebodies consist mainly of pyritic Pb–Zn ores. Silver minerals are associated with Pb–Zn mineralization. Ag-bearing Pb–Zn ores in the deposit are characterized by Ag > Cu > Sb content. Silver occurs mainly as silver minerals, such as minor argent...

Abstract The Herberton Mineral Field in Northeast Australia hosts world class magmatic-hydrothermal Sn–W polymetallic deposits that are enriched In. Baal Gammon and Isabel from the contains early tin, as cassiterite, overprinted by sulfide mineralization chalcopyrite, sphalerite, galena, pyrrhotite, stannite. We investigated distribution of In ores these two deposits, calculated temperature for...

Grinding is generally carried out in wet conditions, but issues regarding water conservation and high-water treatment costs encourage the application of grinding dry conditions. Both produce products with certain characteristics that affect success next process. P100 6 mesh (3.36 mm) ore was performed using steel ball media 33.33% solids for 5, 10, 15, 20, 25, 30 minutes. Particle size distribu...

In this study, surface chemistry and flotation properties of the gold-bearing galena pyrite minerals Menderes region, Izmir, Turkey were investigated with use xanthate-thiocarbamate-monothiophosphate collectors. context, micro-flotation experiments, zeta potential, bubble-particle attachment time measurements conducted in presence Thiophosphate (Aero S-8045), Xanthate (SIBX), Thiocarbamate floa...
