After finding out how Xeon mining of niobium would have the negative impact and some benefits to the indigenous tribes not forgetting the benefits the corporation would get, Demarco was in a predicament.
Mining is an inherently invasive process that can cause damage to a landscape in an area much larger than the mining site itself. The effects of this damage can continue years after a mine has shut down, including the addition to greenhouse gasses, death of flora and fauna, and erosion of land and habitat.
mineral concentrate of pyrochlore (niobium and tantalum). GMMA is a Malawian company owned by Globe Metals and Mining (UK) Limited that is owned by Globe Metals and Mining Limited an Australian based company. Globe had submitted is original Environmental Impact Assessment (EIA) consistent with the Environmental
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. The material is concentrated through wet gravity techniques, gravity ...

Niobium in solid form has no impact on human health, however the dust produced by niobium titanium dust causes eye and skin irritation. Fortunately, there are no reports of human being poisoned by it. If dust is inhaled, it is advised to move to location with fresh air, and if the dust enter the eye, immediately wash with cold water.
Niobium (Nb; atomic number 41) is a critical element, primarily used as an important additive/strengthener in the highvalue steel making process. There are only three niobium producers globally (2 in Brazil, 1 in Canada), all privately held and highly profitable. NioBay Metals Inc. has an impressive niobium resource deposit at James Bay with ...
The recycling of scrap is one of the common approaches aiming at reduction of miningbased production of critical metals and mitigation of their supply risk as well as processingrelated environmental impact. The number of currently available endoflife vehicles (ELVs) indicates—significant potential for critical metals recycling, especially niobium (Nb).
