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.
