PROCESSO PARA O APROVEITAMENTO DE CONCENTRADOS OU MINERIOS COMPLEXOS OXIDADOS QUE CONTEM FERRO DE BAIXO TEOR

A process for the exploitation of low-grade oxidic and iron-bearing complex ores or concentrates, whereby the initial materials are reduced in a rotary kiln at a temperature of 1000 DEG -1500 DEG C. in such a manner that the products are a magnetic fraction primarily consisting of iron, and a non-ma...

Zusammenfassung:A process for the exploitation of low-grade oxidic and iron-bearing complex ores or concentrates, whereby the initial materials are reduced in a rotary kiln at a temperature of 1000 DEG -1500 DEG C. in such a manner that the products are a magnetic fraction primarily consisting of iron, and a non-magnetic oxide fraction, the materials present in this fraction being further exploitable by conventional methods.
