Scheelite (CaWO4, Calcium Tungstate) is an important ore of tungsten which is a strategically important metal. Scheelite is named after the discoverer of tungsten, K. W. Scheele.
The whole mining operation in Mittersill is situated in a protected landscape. Therefore, all the social facilities, workshops and warehouses are installed underground. The ore is crushed underground. The mine and the mineral processing plant are connected by a 3 km long gallery. The ore is transported from the crushing station to the mineral processing plant by a conveyor belt system.
The main mining methods used for the extraction of the massive orebody are:
cut and fill.
The waste-rock which is mined during the development of the orebody is dumped into open stopes underground. There are no waste-rock dumps on the surface. Tailings are used for backfilling of the open stopes.
Scheelite Ore Processing
The ore is crushed to <14 mm by means of a three stage crushing system, situated underground. The crushed ore is then stored in two underground ore bins before being transported to the mineral processing plant by a conveyor belt system situated in a 3 km long gallery. Just beside the mineral processing plant there is a stockpile dimensioned so as to secure the supply of the process with ore for discontinued production at the crushing plant.
The top size of the feed is further reduced to <10 mm in a one stage crushing system consisting of a cone stone crusher which operates in closed cycle with a vibrating screen. The crushed ore is stored in two ore silos from where the ore is fed to a single stage ball mill at a feed rate of 80 82 t/h. To achieve sufficient liberation of the scheelite from the gangue, the ore has to be ground to 80 % passing 180 ѕm. The mill discharge is pumped to a classification system, which consists of screens and a hydrocyclone. The fines with a top particle size of 500 ѕm are pumped to the flotation process, the coarse fraction is recycled to the ball mill.
Flotation consists of one rougher bank and four cleaning stages. A concentrate with an average grade of 40 % WO3 is produced. The rougher tailings are pumped to a hydrocyclone. The cyclone underflow, which contains coarse and intergrown scheelite is recycled to the ball mill for regrinding, the hydrocyclone overflow represents the final tailings stream. The collectors used for flotation are fatty acids (carboxylates), alkyl sulphonates and alkyl sulphate.
