Vulcanization of Heavy-Metal Waste
360ip Partner’s invention is a novel process for vulcanizing heavy metal waste and recovering valuable metals from the heavy-metal waste. The method adopts the hydrothermal vulcanization mode by which the vulcanization rate of the heavy metals increases to as high as 90% and produces little secondary pollution.
The technology involves mechanical activation treatment, hydrothermal vulcanization and sulfur ore floatation.
The technology has the following benefits:
Cost-effective process with the use of low-cost vulcanizer materials.
Generated sulfide has small size and high degree of crystallization, which enables a high-yield floatation recovery process.
Short vulcanization time and high vulcanization rate of heavy metals.
Low waste water pollution.
