Flotation of minerals, an important part the chain metals production for our society, needs huge amounts water. This industry can contribute to sustainable use water and circular economy development by utilizing its own wastewater. However, reuse clarified without additional treatment may cause worsening flotation results. Electrocoagulation this with mild steel sacrificial anodes, complemented...

Mining extraction operations generate a large number of tailings that contain different mineral phases such as quartz (principally), complex silicates, metallic elements, etc. Tailings impose serious concern it is possible to have acid mine drainage potential, leaching, and percolation events heavy metals into the environment under certain conditions. The objective this work was evaluate techni...

This study is focused on the froth flotation reprocessing of a copper mineral from tailings. The effects parameters including pulp density, collector dosage, frother and dispersant dosage were statistically examined to obtain an effective approach for concentrating minerals. sample ore used in this was mainly wastes that have been stored more than 30 years comprised mixed sulfide minerals parti...

Pollution of the environment with toxic metals is widespread and often involves large volumes of wastewater. Remediation strategies must be designed to support high throughput while keeping costs to a minimum. Biosorption is presented as an alternative to traditional physicochemical means for removing toxic metals from wastewater. We have investigated the metal binding qualities of two biomass ...

The coal mining industry is an industrial activity that impacts the environment. This will generate acid mine drainage due to interaction of water, air and sulfide minerals. Acid wastewater with low pH heavy metals content. These conditions be given some negatives impact on environment human health. low-cost, applicable simple method solve in areas constructed wetlands. Hence, this paper aims d...

Abstract: Fluorite is an important strategic mineral. In general, fluorite ores will contain a certain amount of calcite gangue mineral. Thus, they need to be separated from each other. For an economic separation, a reverse flotation process is used to float calcite gangue from fluorite. However, little information on the separation is available. In this study, a novel reagent schedule using ci...

Iron ore concentrate sales in a mineral processing plant appeared a trend of high sulfur, exceeding the sales requirement of 0.3% significantly. To this end, for the sulfide in iron concentrate mainly exists in the form of pyrrhotite, companies with iron minerals and has a high degree of oxidation, we can add flotation agent to the magnetic separation column, and at the same time fill gas for s...
