  • How a coal washing plant produces high-purity CaCO 3?
  • 95% of the silica and alumina impurities removed and generates high-purity CaCO 3. Indian coal washing plants face tremendous pressure in maintaining clean coal yield and handling the rejects. Conventional coal washing plants generate clean coal with 15–18% ash content and 35–50% yield by several physical beneficiation techniques.
  • What is the commercial viability of coal chemical leaching?
  • The commercial viability of the coal chemical leaching process depends on the efficient regeneration of spent reagents such as spent caustic and acid solutions, lowering energy consumption, and value-added products generation from solid wastes.
  • Where is Pam used in water treatment & sludge dewatering?
  • PAM used as a flocculant in water treatment or sludge dewatering is disposed in high-solid biogas digestors or landfills. 94 Although PAM is typically considered to be relatively recalcitrant to organic decomposition, 95 it can be degraded during anaerobic digestion.
  • What is the ash constituent analysis for all three coals?
  • Proximate analysis and ash constituent's analysis for all three coals are tabulated in Tabe-3. All the three coals are having high ash content ranging from 36 to 60%. Since lower particle size shows better leaching performance, therefore, all the coals are ground and screened through −500μ mesh.
