In this study, Taguchi method was used to optimize the optimum conditions of the froth flotation process. The Taguchi optimization shows that the gold recovery was strongly influenced by the particle size which is the best particle size at 150 mesh followed by the Potassium amyl xanthate concentration, pH and pine oil concentration at 1133.98 ...
Coarse particle flotation & regrind circuit
In this way, the flotation circuit enables energy savings plant wide. Additionally, coarser grind size facilitates dewatering and allows for quicker water recovery. Water that traditionally would be lost due to evaporation and seepage no longer end up in tailing and a larger proportion of water can be recovered within minutes versus hours or days.
Pressure Leaching of Copper Slag Flotation Tailings in …
In this study, a hydrometallurgical method for the recovery of copper, cobalt, and zinc from copper slag flotation tailings (SFT) was investigated. SFT contains large amounts of valuable metallic compounds, such as copper, cobalt, and zinc. A representative SFT sample containing 0.50% Cu, 0.148% Co, 3.93% Zn, and 39.50% Fe was used in …

Flotation specificity of coal gasification fine slag based on release
This study draws the following conclusions: (1) The optimal conventional flotation results were obtained at the diesel dosage of 16 kg/t and the MIBC dosage of 8 kg/t, with the flotation perfect index of 41.12%. In the step release flotation under these conditions, C 3 has the lowest ash content of 29.21%.
Recovery of zinc and lead from Yahyali non-sulphide flotation tailing
Based on the sequential leaching experiments, the zinc and lead were excellently depleted from the flotation tailing, leaving a considerable amount of iron in the final residue.

Flotation of a refuse tailing fine coal slurry
The results showed that the refuse tailing fine coal slurry was very straightforward to upgrade by flotation. Flotation yield of 45% (dry basis, db), combustible recovery of 92%, product ash of 20%, db and separation efficiency of 79% were obtained when MIBC was used as frother and kerosene as collector. Those results are in …
Potentially Exploitable Reprocessing Routes for Recovering
Abstract This research aimed at recovering metals retained in the tailings from the flotation of copper (Cu) and cobalt (Co) ores conducted at the New Concentrator in Kipushi (NCK). Metals retention in the tailings (0.73% Cu and 0.37% Co) increased due to the removal of the gravity separation section from the processing circuit together with …
