The flotation behavior of a refuse pond fine coal slurry sample was studied using mechanical and column flotation techniques
The flotation process performance of a refuse tailing fine coal slurry sample from a Colombian washing coal plant was studied using a mechanical flotation technique Flotation parameters investigated included dosage of frother methylisobutylcarbinol MIBC and collector kerosene as well as scrubbing time for the mechanical flotation cell
A Flotation Study Of Refuse Pond Coal Slurry We are a largescale manufacturer specializing in producing various mining machines including different types of sand and gravel equipment milling equipment mineral processing equipment and building materials equipment
Jun 11 2020 · The present flotation study was undertaken as part of the efforts to develop an effective fine coal cleaning circuit to recover fine coal from a refuse pond Flotation parameters examined included type and dosage of frother and collector agitation speed scrubbing time and slurry pH for the mechanical flotation cell and air flow rate feed flow rate and wash water flow rate for the column flotation
The coal samples treated in this study were a minus100 mesh flotation feed slurry a minus40 mesh coal and a refuse pond coal sample This investigation found that the Packed Column Jameson Cell and Microcel are the best flotation columns for cleaning the Illinois Basin coals
A recent study conducted by the National Research Council under congressional mandate reports some 70 to 90 million tons of fine coal are being discarded to coal slurry impoundments annually by the US coal industry
Cyclomicrobubble flotation column CMFC is an advanced column flotation technology for fine coal cleaning developed by China University of Mining and Technology CUMT It combines cyclone
Several tons of refuse tailing fine coal slurry are produced in Colombian coal cleaning plants which are usually discarded in refuse ponds Any strategy to recover and utilize the organic matter present in the refuse tailings slurry could represent an important energy source having environmental and
Thickener DPT for dewatering of fine coal refuse Their study showed that using a proper addition of anionic and cationic flocculants to the slurry before it is fed to the Deep Cone Thickener produced a dewatered paste product containing about 50 solids Figure 3 and 4 show the Deep Cone Thickner in operation and the paste produced
dewater coal fines below 44 microns” says Yoon “Now this technology can be used to remine the fine coal discarded to impoundments and to help companies minimize waste generation “For me that is a great accomplishment” says Yoon “People living in coal mining districts will see fewer and smaller slurry ponds
In this article experiments were conducted under various working conditions in order to recover coal from waste coal slurry by cyclojet flotation Waste coal slurry with 4750 ash yielded
Apr 24 2013 · Many of the manmade ponds for storing toxic sludge from coal mining operations have dangerously weak walls because of poor construction methods according to the synopsis of a study

This paper reports the demineralization of coal with EDTA citric acid HCl HNO3 acid mixture and CH3COONH4 The residual coal from each treatment was analyzed using Scanning Electron Microscopy All the micrographs are bright field and reveal several features correspond to the mineral grains comprised of lithophiles like aluminum potassium and sodium sidrophiles like iron and
Paste thickeners produce thick underflow “paste” which is stable and will not flow or leach material when exposed to rain This allows coal waste impoundment elimination along with the associated costs and risks of maintaining such waste ponds Read a case study about the remediation of coal refuse ponds through the use of paste thickeners
The thickened refuse or sludge underflow may be pumped to waste ponds or if water is in short supply filtration of this refuse may be necessary Coal flotation concentrates produced in this primary section are filtered direct and the filtrate is recycled back to the flotation cells for reuse
Oct 21 2016 · Flotation is a complex multifaceted process that is widely used for the separation of finely ground minerals The theory of froth flotation is complex and is not completely understood This fact has been brought many monitoring challenges in a coal processing plant To solve those challenges it is important to understand the effect of different parameters on the fine particle separation and
