Zinc adsorption kinetics by phosphogypsum — A preliminary study
Materials and Methods PG, obtained from TÜGSA^ Fertilizer Plant in Samsun, Turkey, was sieved (particle size, 65 mesh) and then preconditioned with lime milk. Physical and chemical characteristics of raw and lime-preconditioned PG have been published. Aqueous solutions (100 ml) containing Zn ions (50 mg/l) were taken in Erlenmeyer flasks (250 ml) containing lime-preconditioned PG (1 g). These f...
متن کاملProcessing of Low Grade Fine Manganese Ore Using Flotation Method
Application of gravity and magnetic separation methods to upgrade low grade Manganese ores from Venaj Mine has been reported elsewhere. This paper discusses the results of flotation tests, as well as combination of flotation and magnetic method to concentrate fine particles (less than 150 microns) of manganese ore. Results obtained from various direct and reverse flotation tests, using differen...
متن کاملTreatment of phosphogypsum waste using suitable organic extractants
Phosphogypsum (PG) is a residue of the phosphate fertilizer industry that has relatively high concentrations of harmful radioactive materials. The reduction in concentration of the radionuclides from PG was investigated. The removal process is based on leaching of radionuclides using suitable organic extractants. The studied radionuclides were 226Ra, 210Pb, 238U and 40K. The factors affect the ...
متن کاملEnvironmental Risk Assessment System for Phosphogypsum Tailing Dams
This paper may be of particular interest to the readers as it provides a new environmental risk assessment system for phosphogypsum tailing dams. In this paper, we studied the phosphogypsum tailing dams which include characteristics of the pollution source, environmental risk characteristics and evaluation requirements to identify the applicable environmental risk assessment methods. Two analyt...
