Application of Flocculant and Coagulant to Coal Slime Water
Advanced Materials Research, 2013Through the analysis of size composition, ash and other properties of Qidong coal mine, three kinds of coagulants and flocculants are used to do the settlement test. The concentration of coal slime water, the types and effect of flocculant and coagulant on the settling are also studying.

A New Method to Evaluate the Performance of Slime Water Treatment
Energy Sources, Part A: Recovery, Utilization and Environmental Effects, 2016ABSTRACTSlime water is used repeatedly and its treatment is very essential in coal preparation plants. A new method called fractal dimension is proposed to evaluate the performance of slime water treatment. According to settling experiments, the settling process of slime water can be divided into two phases.

Slime Coating of Kaolinite on Chalcopyrite in Saline Water Flotation
International Journal of Minerals, Metallurgy and Materials, 2018In saline water flotation, the salinity can cause a distinguishable slime coating of clay minerals on chalcopyrite particles through its effect on their electrical double layers in aqueous solutions. In this work, kaolinite was used as a representative clay mineral for studying slime coating during chalcopyrite flotation.

Effects of Coal Slime on the Slurry Ability of a Semi-Coke Water Slurry
Powder Technology, 2020Abstract As a by-product of the coal washing process, the methods involving the resource utilization of coal slime are very few because of its strong agglomeration and large water content. In this work, we propose a new way to dispose of coal slime, which involves preparing semi-coke water slurry (SCWS) with coal slime.

Optimum Conditions to Treat High-Concentration Microparticle Slime Water With Bioflocculants
Mining Science and Technology, 2010Abstract We studied how bioflocculants, produced by white-rot fungi, affect flocculation in slime water. Based on a test in an orthogonal design, flocculation conditions were optimized. The results show that flocculation activity is at its highest when the following conditions are met: slime water concentration 27.42 g/L; coagulant aid (CaCl2) mass ...

Earth and Water in the Slime of World War I Trench Warfare
, 2009 From the American Civil War, the first war of the industrial age, to World War I (WWI), ‘the first big war fought between industrialised societies’ (Carlyon, 2006, pp. 761–2), a shift occurs in the type of warfare being conducted, not just in the scale of industrial technologies brought to bear in and on it. A mobile war fought through and over several

Water or slime? A platform for automating water treatment systems
Proceedings of the 1st ACM Conference on Embedded Systems for Energy-Efficient Buildings, 2014Worldwide, the availability of water is increasingly becoming a political and environmental concern. With a quarter of the world's population living downstream of the receding Himalayan glaciers [1], tensions over availability of fresh water supplies will only rise in the coming years.

Effect of magnetization pretreatment of coal slime water flocculating sedimentation
International Journal of Coal Preparation and Utilization, 2021Sedimentation of coal slime water (CSW) is an important process in coal processing plants. However, CSW is difficult to settle because of its high content of clay minerals and fine particles.

The Sedimentation Experiment of the Fine White Slime Water
Advanced Materials Research, 2013There are a lot of white ore in Jixi Qingshan coal mine. Argillization of this ore is very terrible. This ore quickly turns to fine white slime in water and forms the stable suspending liquid. It leads that slime water form sediment is very terrible. This paper analyzed and researched the characters of the fine white slime water. The experiment results

The flocculation and de-watering of kimberlite clay slimes
International Journal of Mineral Processing, 1974Abstract The crushing of kimberlite at certain diamond mines produces a very persistent “slime” which is exceptionally difficult to filter or de-water. The colloidally stable component has been identified as a swelling clay, saponite, which carries a strong negative charge in alkaline media.
