Abstract
A process for extracting metal values from ores or residues is disclosed. The process mentioned above is mainly suitable for aluminoferrous ores such as bauxite, titanoferrous ores such as ilmenite, or residues such as red mud waste. The process involves pulverizing the ore and/or residue and mixing with a carbonaceous material, followed by smelting the iron values and slag in the mixture to yield molten iron and oxides of aluminum and titanium. The process is simple, cost-effective, and provides effective extraction of high purity metal values.
Claims15
A process for extracting from a mineral material, which is an ore, a residue, or a mixture thereof, iron value and at least one metal value selected from the group consisting of aluminum, titanium, sodium, calcium, and, silicon, said process comprising the steps of:
- pulverizing said mineral material to a particle size in the range of 5-500μ, to obtain a pulverized material;
- combining said pulverized material with a carbonaceous material to obtain a resultant mixture, wherein, the ratio of said pulverized material to said carbonaceous material is in the range of 88:12-95:5;
- moulding said resultant mixture to obtain a formed material in a form selected from the group consisting of pellets, lumps, and briquettes;
- smelting, at least partly, metal and slag in said formed material, to separate the iron values along with the slag containing at least one metal value selected from the group consisting of aluminum, titanium, calcium, sodium, and silicon;
- and
- separating the iron values from the slag.
