paper. Silty tailings samples from Stava (Italy) fluorite extraction were chosen. Dry and wet samples were exposed to gamma rays from a 60Co source up to a dose of 1000kGy in order to simulate the aging process in two extreme cases: dry conditions if tailings are used for bricks, wet conditions for tailings de-posited within the storage ...

Fluorite is a common accessory mineral in the ore and tailings. Our objective was a preliminary evaluation to produce a high quality quartz concentrate from the approximately 2 million tons of tailings present. Shallow drilling and pits <6 ft deep recovered ~60-pounds of wet tailings from gridded sites on the tailings

The ratio of tailings to concentrate is commonly very high, generally around 200:1 (Lottermoser, 2007).Moreover, as the point of peak metal production is surpassed, the extraction of lower grade ore is an established long-term trend (Mason et al., 2010).For example, in Australia the average Cu grade was c. 10% in 1885 but it fell to 1% by 2005, whereas in Canada the average Ni grade was c. 5% ...

Focusing on the tailings containing high sodium silicate (water glass), this study conducted laboratory experiments and semi-industrial tests of flocculation and sedimentation for rapid tailings dewatering. Various reagent combinations, lime and anionic flocculant (APAM) (L&A), sulfuric acid and APAM (S&A), and calcium chloride and APAM (C&A), were tested.

An internal standard of 10 wt % fluorite (CaF 2) was added to a subsample of each tailings sample. The internal fluorite standard along with structureless pattern fitting (independent of atomic scattering) provided a means of quantifying the abundance of the poorly ordered serpentine in the tailings using the method of Wilson, Raudsepp and Dipple .
