Industrial value minerals tantalum and niobium tantalum iron ore, columbite, pyrochlore, fergusonite ore, gold ore dilute black, calcium, cerium, niobium titanium ore. The type of antimony ore is roughly divided into coltan-niobite ore, chlorite ore and other antimony-bearing ores.
ore.
The rough selection of antimony ore is mainly re-election. In addition to niobium minerals and zircon , the coarse concentrate also contains magnetite, ilmenite, monazite, quartz , mica , garnet, tourmaline and limonite. A variety of minerals, complex composition, difficult to sort, often require a combination of magnetic separation, re-election, floating re-election, flotation, electrification, chemical treatment and other methods.
The specific magnetic susceptibility of the coltan is 2. 4 × 10
The following picture shows the selection process of the coarse concentrate of Guangxi Lisong brown ore. The selection uses a magnetic separation-reselection-floating reselection combination process. The coarse concentrate is first dried, then it is fed into a single-disc magnetic separator to select iron filings. The other enters the three-plate magnetic separator. The magnetic properties of various minerals are used to strictly control the operating parameters and the minerals are divided into ilmenite-brown. Yankuang Formation, brown earth mine-monupolis group, monazite-brown ore group and zircon group. The first three groups of materials are first pickled and then shaken-magnetically selected or magnetically selected. The selected magnetic materials are halophilized with oleic acid, sodium carbonate and sodium silicate. The product in the tank is brown ore. The latter group used a shaker-magnetic separation-shaker to sort out the brown ore and zircon concentrate. The index is: brown pelagite concentrate Nb 2 O 5 ) grade 35.72% , concentrate recovery rate 87.62% ; monazite concentrate ( TR 2 O 3 + ThO 2 ) grade 65.23% ; zircon concentrate ( ZrO 2 ) The grade is 60.48% ; ilmenite is also recovered.
