Class 12 CHEMISTRY Chief ore of `Zn` is `ZnS`. The ore is c...Chief ore of Zn is ZnS. The ore is concentrated by froth flotation process and then heated in air to convert ZnS to ZnO. ltntgt 2ZnS+3O2→2ZnO+2SO2…(i)
1.1 Basic concept of flotation process Flotation process, where the separation of minerals from complex ores is based on the difference in their hydrophobic features, is performed at the contact of three phases: solid–liquid–gaseous. In this three-phase system (usually, this system consists of ...
Both first-principles and data-driven machine learning methods have been used to model the flotation process. The complexity of models based on first-principles restricts their direct use, while purely data-driven models often fail in dynamic industrial environments, leading to poor generalization. To...
At present, the coal flotation process relies on artificial recognition of froth features for adjusting the reagent dosage, which cannot realize the optimal control of the quality of the clean coal product and the cost of the reagents. Therefore, in this paper, it is proposed a method of ...
the froth zone [1, 3, 6]. This process has important implications in terms of overall flotation performance impacting both the quality (the grade) and quantity (the recovery) of the particles delivered from the pulp and froth zones to the concentrate [7]. The difficulty of ...
838,302. Froth flotation. POTTER, W. W. (Mining Process & Patent Co.). Feb. 15, 1957, No. 5171/57. Class 82(2) A froth flotation apparatus incorporates two impellers 20, 22, the upper one of which forms an air vortex 27 and also expels part of the air sucked down the tube ...
NaCN is sometimes added in the froth flotation process as a depressant when ZnS and PbS minerals are expected because : APb(CN)2 is precipitated while no effect on ZnS BZnS forms soluble complex Na2[Zn(CN)4] while PbS forms froth CPbS forms soluble complex Na2[Pb(CN)4] while ZnS forms...
This invention relates to a process for concentrating minerals and more particularly to a froth flotation process for concentrating non-metallic minerals. Heretofore, fatty acids, soaps, or analogous
As well known in the art, froth flotation processes utilize differences in the surface characteristics of the ore and the refuse to effect separation. When used to separate coal from refuse, the process takes place in a large vat or cell containing a separating medium which is composed largely...
