mining is by conventional open pit, selective, methods. overburden is removed by power shovel and trucks and mineralized horizons by ripper and front-end loader. beneficiation plant consists of crushers, screens, ball mills, cyclones and flotation to produce an acid grade product for export. metallurgical grade fluorspar is sold locally.
Dec 24, 2015· He says: "We are one of the last three or four producers in the EU producing Fluorspar, so I've been looking at how we operate sustainable mining operations and we are now moving back to an underground mining model from an open pit mining model for producing our ore."
The mine's concentrator will produce around 180 000t of acid grade fluorspar (97% pure fluorspar) and 30 000t of metallurgical grade fluorspar annually from run-of-mine fluorspar ore production of 630 000t. Open-pit mining and modern plant efficiency is expected to put .
Most mining was underground, as much as 1,300 feet deep. But open-pit mines operated where fluorite deposits intersected land surface. Illinois displaced Kentucky as the country's leading producer of fluorite in 1942. For many years, Illinois accounted for more than 50% of total U.S. fluorspar production.
Fluorspar is planned to be mined in a combination of open pit and underground mining operations. For the future, Gecko envisages a metallurgical process with dual product output, high grade acid spar and low grade metallurgical spar, to efficiently use the fluorspar resources.
