Apr 24, 2017· Most tantalum mines are open pit; some are underground. The process of mining tantalum involves blasting, crushing and transporting the resulting ore to begin the process of freeing the tantalum. The ore is then concentrated at or near the mine site, to increase the percentage (by weight) of tantalum oxide and niobium.
Tantalum and niobium processing can be difficult because the minerals are brittle, heavy and typically highly intergrown with sulfide and other oxide minerals. SGS has contributed to many tantalum projects over the years and can bring an integrated suite of services to tantalum and niobium exploration or development projects. Mineralogy
The mining of battered ore, operation between 2.5 and 3.0% Nb2O5, is performed by easy open pit mining devoid of the requisite for drilling and explosives. Roughly 85 to 90% of the niobium industry expands its niobium ores from resources other than those connected with the mining of tantalum .
Jan 13, 2010· Indeed, until the discovery of the world's pyrochlore deposits in the 1950s, niobium was a by-product of tantalum mining, with increasing demand ensuring that it was highly valued and highly priced. All of the world's main tantalite mines are hosted in pegmatite ore bodies, including Wodgina, Greenbushes, Marropino and Bernic Lake in Canada.
