Description

A device for reducing pyrolusite by microwave heating biomass

technical field

The utility model relates to a device for reducing pyrolusite by microwave heating biomass, which belongs to the field of microwave metallurgy.

Background technique

In recent years, with the sharp increase in the demand for manganese products, low-grade manganese oxide ore, oceanic polymetallic manganese nodules, and secondary manganese resources have been studied and utilized as important resources. Most of the traditional smelting methods are high-temperature pyrometallurgical smelting processes. Due to the high energy consumption and serious environmental pollution of the pyrochemical reduction process, it is not suitable to use the traditional reducing agent to adopt the high-temperature pyrometallurgical smelting process from an economic point of view. Based on the existing technology, the utility model adopts microwave heating instead of traditional heating, and replaces traditional coal powder and other reducing agents with biomass reducing agent, which can reduce the required temperature, realize clean and green heating and reduce manganese oxide, so as to reduce production capacity Consumption and cost.
