1.A process for recovering at least one metal oxide from a titaniferrous or aluminaferrous mixture comprising:(A) preparing a molten slag, said molten slag is prepared by(A1) melting iron with a composition of cast iron into a molten cast iron bath;(A2) adding said titaniferrous or alumi...
To answer the question about the constituents of the electrolyte for the extraction of aluminium, we can follow these steps:1. Identify the Main Component: The primary constituent of the electrolyte used in the extraction of al
A method of producing gallium from gallium-containing dust (e.g. dust which is recovered from gas collecting systems in plants for the electrolytic production of aluminium) comprises leaching the dust in an aqueous hydrochloric acid solution (e.g. at a temperature between 50 DEG and 120 DEG C...
Bayer red mud is a strong alkaline solid waste discharged during alumina production. Due to large emissions and strong alkalinity, red mud is now mostly dammed or buried, which not only occupies huge land but also contaminates the surrounding ecosystem, causing the risk of collapse and landslide...
