ABSTRACT. The solubility of low-grade zinc ores with a selective leaching environmentally friendly reagent has become focus great interest since and its compounds have found wide application. For this purpose, lactic acid was used to investigate the kinetics smithsonite ore obtained from Kayseri region. effects particle size (137.5-725 µm), concentration (0.5-5 M), solid/liquid ratio (0.5/250-3...

The Huoshaoyun zinc–lead deposit, a giant non-sulfide deposit in Xinjiang, is one of the most significant discoveries China and globally recent years. dominated by non-sulfides, with minor occurrences sulfides such as sphalerite, galena, pyrite. minerals include smithsonite, cerussite, anglesite, Fe-oxide. This study focuses on mineralogical characteristics sulfide ores, well trace element Mine...

Pulp rheology is an important factor affecting flotation. The effects of particle size (150-74 μm, 74-38 38-23μm, -23 μm), pulp density (11.76%-34.78%), pH (5.3-12.4), collector concentration (25-500 mg/dm3), and stirring intensity (400-900 rpm) on the smithsonite, kaolinite, quartz, calcite minerals were investigated in detail. Additionally, agglomerate morphology particles was observed by a p...

Smithsonite exhibits an extensive range of colours in nature. The internal features, spectral characteristic, and trace elements several coloured smithsonites (e.g., white, blue, blue-green, yellow, orange, pink) from Lanping District, Yunnan Province, China, were analysed the relationship between smithsonite colour and/or impurities was discussed this research. presence iron manganese closely ...

Gardaneshir Pb–Zn deposit is hosted by dolomitic carbonates which is located in the SW Ardestan, central Iran. Ore body is stratabound type in this deposit. Primary ores in this type are composed of sphalerite, galena, barite and quartz with massive, banded, veined and disseminated structures. Evaluation of ore-grade at the Gardaneshir Pb-Zn deposit, based on chemical analysis which indicates a...

The plant species Pinus halepensis grows spontaneously on heavily polluted mine tailings dumps of Campo Pisano (Sardinia, southwestern Italy). area is characterized mainly by Zn, Pb, and Cd. Sampling campaign was done, related to soils materials (roots, barks, wood, needles), aimed at evaluating the main mineralogical characteristics, metal content, accumulation, translocation behavior. substra...
