The great difference between E Cu and E Fe in concentrate and tailing indicates the good separation of copper and iron in the sulfuring flotation beneficiation process. The high E Cu suggests that the addition of sulfiding agent Na 2 S may increase copper recovery ( Sibanda et al., 2020 ).

The mineral composition of copper–cobalt ores is more complex than that of copper sulfides, and it is also difficult to discard tailing efficiently in primary flotation for the fine-grained disseminated of ore. In this work, a mineral liberation analyzer (MLA) was employed to study the characteristics of minerals. As a significant mineralogical …

Floatation tailings (FT) are the main by-products of the hydrothermal sulfidation–flotation process. FT (FT1 and FT2) were obtained by treating two different neutralization sludges (NS) (NS1 and NS2). This paper quantitatively evaluated the environmental risks of heavy metals (Zn, Cd, Cu, Pb, and As) in FT versus NS. The total …

A new flotation tailings treatment process was developed for efficient Cu recovery. • An efficient Cu dissolution was achieved in an H 2 O media in presence of pyrite.. The dissolution mechanism of CuFeS 2 has been confirmed to be a multistage reaction.. Fe was always co-dissolved with Cu following a linear relation of C Fe = 38.393 …

The mass production of flotation tailings has become a serious risk to the environment. Re-concentration of tailings is one of the best ways to solve this problem, which requires a better understanding of flotation tailings. In the present work, flotation kinetics, timed-release flotation, X-ray dif …

Abstract. Phosphorus ore flotation tailings (POFTs) are an industrial solid waste generated in the process of phosphate mining, which contains a large number of …

Abstract. Neutral oils like kerosene, diesel, transformer and rapeseed oil were used as collectors or bridging reagents in conventional flotation and oil agglomeration flotation (OAF) process, and a promising OAF process has been developed for the recycling of ultrafine molybdenite resources from the waste tailings.

Abstract. This study presents the exploratory results on the nickel extraction from a serpentine flotation tailing sample containing sulfide and serpentine minerals at 0.3 wt.% of nickel. The nickel deportment analysis showed that almost 60% of nickel is hosted by sulfur-based minerals and 40% of nickel is in serpentine phase.

Yu et al. 15 proposed a separation process of coal flotation tailing, namely reverse flotation–grinding–re-separation, to obtain the clean coal product with a yield of 25% and an ash content of 13.96%. It is worth noting that the above re-separation processes of coal flotation tailing all include a grinding stage. The carbon component in ...

The resource utilization of cyanide tailings has significant environmental and economic benefits. The efficient recovery of gold from low-grade cyanide tailings containing 1.71 g/t Au was performed by a chlorination roasting–flotation process.
