Pyrite Ore 3-35mm plays a crucial role
Pyrite Ore 3-35mm plays a crucial role as a key auxiliary agent in the roasting and recovery process of non-ferrous metal solid waste, with its functions mainly reflected in the following aspects:
- Providing heat source and reductive atmosphere
- Promoting the sulfidation and volatilization of target metals
- Immobilizing harmful impurities
- Improving the physical properties of furnace charge
Typical application scenarios
Recovery of copper/lead/zinc smelting slag: When treating smelting slag containing trace amounts of non-ferrous metals, the addition of pyrite can enhance the sulfidation and volatilization of metals such as copper and lead.
Roasting of electronic waste: Facilitating the dissociation of precious metals (e.g., gold, silver, copper) from complex matrices and their enrichment through sulfidation reactions.
Treatment of arsenic-containing waste: Immobilizing arsenic by utilizing the iron-sulfur system to reduce toxicity risks.
