Copper smelting slag is produced from copper pyrometallurgy (both smelting and converting stages), usually grading at 0.3-3%. The slag may also contains lead & zinc minerals like galena, sphalerite. Copper mainly dwells in the slag in the …
The smelting process can be divided into three stages, namely decomposition of high-valence sulphide, oxidation of sulphide, and matte smelting and slagging reaction (Fig. 1).The efficiency of matte smelting and matte-slag separation, as well as the extent of copper losses to slag are mainly affected by the oxidation/reduction potential, matte grade, smelting …
Moreover, SMS group is working on innovative concepts to boost recycling rates. Electric slag cleaning furnaces are primarily used in the nickel, copper, lead, and PGM (platinum group metals) industries, recovering metals from slags. This began in the 1950s when SMS group installed its first units. The units are so successful that more than 40 ...
The SILMA comprises of 50 Lead Recycling units from 5 Southern states Kerala, Karnataka, Tamilnadu, Andhra Pradesh & Telangana. The Total recycling Capacity of SILMA Members is around 7.5 Lakh Tons per Annum which is …
In the present work a cleaner production of alkali activated cement was conducted by recycling blast furnace slag and lead-bearing sludge as aluminosilicate precursors. Lead bearing sludge up to 30 wt % regarded as a good silicate source which was found to have a positive impact on the physical and mechanical properties of alkali activated …
The lead slag recycling apparatus allows the lead slag to be collected through the receiving tank, the receiving tank to be driven by a cylinder to rise and the lead slag in the receiving tank to be poured into the lead slag inlet in order to recycle the lead slag, so the resource waste of an enterprise is reduced, manual operation is not ...

modern lead recycling plants use silica slag (fayalite slag), which is water insoluble. It requires, however, a much higher furnace operation temperature of approximately 1400°C. The refining …
The hydrometallurgical process Conventional recycling uses high-temperature smelting at around 1 200 degrees Celsius to yield 98 % molten lead metal and slag, which also produces high levels of nitrogen oxide (NOX), sulphur oxide (SOX) emissions and lead fume, which must be controlled by gas treatment systems.
The lead produced in Brazil comes entirely from the lead-acid battery recycling industry. During the process, 100 to 350 kg of slag is generated for each ton of metallic lead produced. This large amount of waste generated causes serious environmental problems, where reuse and reducing toxicity are measures to resolve its negative impact.
