Flotation Deinking Using flotation method for removing ink from paper during the de-inking process. Flotation Dryer Non contacting dryer used in pulp drying or coating applications, drying is achieved by passing sheet between two dryer hoods where hot dry air is impinged onto the sheet and the moisture is evaporated and removed by an air system. The mineralogical characteristics of enargite-bearing copper ores from the Tampakan deposit have been investigated as the means to understanding the separation of enargite from other copper sulphides (chalcopyrite and bornite). It was found that a separation of these minerals was possible after grinding the ore samples to a P80 of 90 microns; enargite tends to be ground Cited by: 3.
Multiphase systems are important in minerals processing, and usually include solid–solid and solid–fluid systems, such as in wet grinding, flotation, dewatering, and magnetic separation, among several other unit operations. In this paper, the current trends in the process system engineering tasks of modeling, design, and optimization in multiphase systems, are by: 2. The minerals calcium carbonate and talc were filtered under various conditions of filtrate flow rate and suspension concentration, using constant rate conditions with the aid of a peristaltic pump to draw the filtrate. Cake concentrations of between and v/v for calcium carbonate and and v/v for talc were recorded.
A flotation process is disclosed for cleaning of particulate coal and separation therefrom of pyrite and ash. A flotation pulp is prepared comprising a particulate coal feed material and an anionic surfactant selected from among alkanesulfonic acids, alkenesulfonic acids, alkynesulfonic acids, arenesulfonic acids, alkyl sulfuric acids, alkenyl sulfuric acids, alkynyl sulfuric acids, aryl Cited by: This book is designed to cover all the process calculations. The method and/or steps in process calculations have been described by taking numerical examples. Process calculations illustrated in a simple and self explanatory manner based on two basic material balance equations will allow the reader to understand the contents thoroughly.

Get this from a library. Coal-pyrite flotation: a modified technique using concentrated second-stage pulp. [Kenneth J Miller; United States. Bureau of Mines.; United States. Bureau of Mines. Coal Preparation Program.]. The Bureau of Mines two-stage coal-pyrite flotation process was modified to provide a more concentrated final clean coal slurry underflow that could be dewatered economically by filtration or centrifugation.
Coal-pyrite flotation: a modified technique using concentrated second-stage pulp / By Kenneth J. Miller, United States. In this study, the possible use of a ball mill with steel ball media as dissolved Fe source for GME was investigated. Fig. 1 shows a schematic diagram of how GME in a ball mill containing steel ball media and phosphate would work.
Because pyrite is the most common sulfide gangue mineral in the mineral processing of non-ferrous sulfide ores and is the main cause of AMD in tailings Cited by: 3. The Bureau of Mines two-stage coal-pyrite flotation process was modified to provide a more concentrated final clean coal slurry underflow that could be dewatered economically by filtration.

However, the froth product ash and sulfur was fairly high (% ash and % sulfur). For the second stage clean- ing step, the reduction of ash and sulfur was % and I % respective- ly, with an overall recovery of %. The froth product ash and sulfur showed % and %, respectively.

In this study, optimization of coal flotation was made in two stages. In the first stage, classical first-order flotation model was used in order to investigate the modified flotation parameters (K m, SI) of five important Jameson flotation variables, in the second stage, combustible recovery (%) and ash content (%) were utilized.
This experimental design is a new methodology in the Cited by: This was accomplished by doing the first-stage coal flotation step in the conventional manner with a slurry of about 8 percent solids but running the second-stage pyrite flotation step with [Show full abstract] undiluted coal froth concentrate containing about 25 percent solids.
Microorganisms can play a beneficial role in all facets of minerals processing, from mining to waste disposal and management. The commercial practice of biohydrometallurgical metal extraction occurs all over the world.
However, starch was not an efficient depressant for quartz due to the similar depression might have occurred in the flotation of apatite and dolomite. Considering the cost rather than the quality of the product, starch is still widely applied in the flotation of igneous phosphate ores in Brazilian concentrators [ 41 ].Cited by: 3.
In this paper, a pilot-scale Jameson Cell was modified for improving flotation separation of spodumene in high altitude area with low atmospheric pressure. The modified design parameters were the method of forming micro-bubbles by using a micro-porous tube instead of inducing air by the highly pressurized pulp, Cited by: 3.
Combining these two concentrates, the two stage system recovered 86 pet of the coal in a concentrate containing pct ash. While the second stage only recovered 23 pct of the coal, the second stage actually recovered 62 pct of the coal that was still present in Cited by: 6. The Bureau of Mines two-stage coal-pyrite flotation process was modified to provide a more concentrated final clean coal slurry underflow that could.
Gold Ore Processing: Project Development and Operations, Second Edition, brings together all the technical aspects relevant to modern gold ore processing, offering a practical perspective that is vital to the successful and responsible development, operation, and closure of any gold ore processing operation.
This completely updated edition. Abstract. Process of coal slurry dewatering on the vibrating screen surface involves three stages: at the first stage, pulp is concentrated to high concentration due to the removal of free water by the action of hydrostatical pressure applied to its layer; at the second stage, high-concentration pulp is imparted with the viscoplastic properties due to removal of Author: A.
Polulyakh, I. Eremeev, S. Chaplygin. The conventional flotation process was conducted on each sample utilizing kerosene and MIBC. In order to further liberate the pyrite, the froth concentrate was then wet ground to /0 mesh size.
Then a second stage reverse flotation was applied by. Power consumption is one of the critical parameters in optimization of industrial operations.
In the present work, the power draw measurements were used as a method of characterizing and optimizing particle aggregation.
A series of agglomerate flotation and oil agglomeration tests were carried out to find a correlation between power draw, particle aggregation and flotation.
