The aim of the study was to (i) investigate the potential of edible mushroom Boletus badius (Fr.) Fr. to accumulate 53 elements from unpolluted acidic sandy soil and polluted alkaline flotation tailing sites in Poland, (ii) to estimate the low-molecular-weight organic acid (LMWOA) profile and contents in fruit bodies, and finally (iii) to explore the possible relationship between elements and L...

Deep sea mining tailings disposal is a new environmental challenge related to water pollution, mineral crust waste handling, and ocean biology. The objective of this paper is to propose a new tailings disposal procedure for the deep sea mining industry. Through comparisons of the tailings disposal methods which exist in on-land mining and the coastal mining fields, a new tailings disposal proce...

Copper ore is a non-renewable resource with lower grades, which means that the extraction of more rock material required to produce same amount copper, implying greater consumption materials, reagents, water, and energy. Since there copper sulfide present in nature, concentration using bubble flotation method will generate number tailings. This article discusses environmental issues resulting f...

The article presents the results of laboratory studies on ore flotation copper-molybdenum deposits in East Kazakhstan region using a combined reagent. It is required to use new beneficiation methods and reagents increase efficiency minerals improve processing finely disseminated ores. problem can be solved by combination different collectors. objective research recovery copper molybdenum during...

The low grade of copper deposits and the use froth flotation process have caused excessive tailing production. In recent years, experts looked for new alternative methods to improve this situation. Black minerals are abundant resources not exploited by large-scale mining possess high Mn concentrations. On other hand, manganese nodules submarine show concentrations Cu, Ni, Fe, and, mainly, Mn. H...
