COAL FLOTATION Mineral Processing & Metallurgy
Coal Flotation with non-ionic SurfactantsExperimental Materials and MethodsResults and DiscussionSummary and ConclusionsIn coal flotation, the most commonly used collectors are oily materials collectors such as diesel oil and kerosene. For higher rank coals, the reagent consumption in flotation is low because of the high natural hydrophobicity of the coal. However, for low-rank coals (containing a greater amount of oxygen), flotation performance with these oily collectors is poor and large amount of collectors are required in order to obtain acceptable coal recovery.Polyethoxylated nonyl phenols constitut

The Problem with Coarse and Fine Coal BeneficiationThe Problem with Coal Recovery and Cleaning by FlotationCoal Flotation ProblemsCoal Beneficiation ProcessEconomic and operating conditions make it important to provide a simple, low cost, efficient method for recovering fine coal from washery waste. Not only is the water pollution problem a serious one, but refuse storage and disposal in many areas is becoming limited and more difficult. Many breakers and washeries efficiently handle the coarser sizes, but waste the coal fines. This problem is assuming majSee more on 911metallurgist

Physical and chemical interactions in coal flotation
1. Introduction. Conventional froth flotation for fine coal cleaning suffers mainly from two problems: (i) a lack of selectivity for fast floating high rank coals due to the flotation of middlings and entrainment of mineral fines in the froth, and (ii) low recoveries for heavily oxidized or low rank coals due to poor adhesion between bubbles and particles.
Flotation Reagents Mineral Processing & Metallurgy
Flotation Frothers What is the Function of Frothers. The function of frothers in flotation is that of building the froth which serves as the buoyant medium in the separation of the floatable from the non-floatable minerals. Frothers accomplish this by lowering the surface tension of the liquid which in turn permits air rising through the pulp to accumulate at the surface in bubble form.

Floatation of ultrafine coal Froth Flotation (Sulphide
People used to float -0.5mm coal in flotation cells in 1960s,70s and 80s, but now they have switched to -0.25mm flotation. It is recommended that maximum size particle that you try to float be 0.3mm. The reason is that 0.5mmx0.25mm flotation requires more residence time than 0.25mmx0 flotation.
