  • Leaching of toxic elements from secondary alkaline lead

    12-7-2019· Secondary alkaline lead slag (SALS), generated during lead–acid batteries recycling, is a hazardous waste due to its high reactivity, solubility, and migration of toxic elements. After pulverization caused by storage under atmospheric condition for 30 days, the SALS was sieved and coarse fraction (+ 1 mm) was returned to the recycling process.

  • Assessment of Leaching Characteristics of Solidified

    leaching time (12 years) limited the utilization of lead slag as construction materials according to the study of Ettler et al. [14]. However, Saikia et al. [15] confirmed the indication that the lead slag from primary lead production could be used as

  • Leaching of lead slag component by sodium chloride and

    That is to say, first, the lead and its compounds are leached from the lead slag by chloride or alkali. Then, the leaching dynamics of lead slag is studied and the effects of various factors on the process of leaching are evaluated, and finally the leaching elements are transferred into materials, which have application value.

  • Leaching properties of secondary lead slag stabilized

    Sodium lead slag, generated during secondary lead production, is characterized as hazardous waste. The aim of the study was to investigate leaching mechanism and behaviour of lead and arsenic from sodium lead slag previously stabilized/solidified in concrete using additives: MgO, CaO, Ba(OH)2 and gypsum.

  • 12 years of leaching of contaminants from Pb smelter

    Lead slags from two different metallurgical technologies (primary slag from Pb-ore processing and secondary slag from car battery recycling) were submitted to 12-year batch leaching at a L/S ratio of 10 and the leaching data were compared with the previously obtained results from a ⩽1-year leaching test.

  • Preparation of calcium stannate from lead refining slag by

    The lead refining slag used in this study was obtained from a pyrometallurgical smelter of waste lead acid batteries in China. Firstly, the sample were dried at 100 °C for 24 h and then were digested by HNO 3-HCl system for stone composition analysis by Inductively Coupled Plasma Optical Emission Spectrometer (ICP-OES; Thermo Scientific; iCAP 6500; Massachusetts;

  • EXPERIMENTAL INVESTIGATION OF FUNDAMENTAL VISCOSITY

    This slag must be disposed of, but the behavior of impurities from the solidified slag and the physical properties of the molten phase are not well understood. In this work, the leaching characteristics, viscosity, and density of a sodium-iron-silicate system representing a modern secondary lead smelter’s slag have been studied.
