South Africa, where a refractory high-antimony gold ore is being treated, flotation and cyanidation of the flotation concentrates and tailings are being practiced. The association of the antimony and gold is very intimate, and during 1946, while the antimony recovery amounted to 70.6 per cent, only 62.7 ...

Disclosed is a process for concentrating stibnite (antimony sulfide) and separating it from iron sulfide minerals such as pyrite by froth flotation using untreated recirculated water or mine water which is acidic and may be heavily loaded with metal salts. The process features the use of a water-soluble zinc-cyanide complex salt to depress iron sulfide minerals.

Of these, lead ion (usually provided as lead nitrate) is employed as an activator for flotation of nonferrous minerals [[14], [15], [16]]. Results for the flotation of stibnite with Pb 2+ as an activator and xanthate as collector showed that Pb 2+ could adsorb on the stibnite surface and increase the flotation efficiency of stibnite at pH 6.5 ...

Flotation may also prove to be the more economical process for an ore containing such minerals as stibnite, copper-bearing sulphides, tellurides, etc., which require roasting before cyanidation, since it reduces the tonnage passing through the furnace to a fraction of the original feed with considerable reduction of working costs in …

And the composition of concentrate for Sb and As is 52% and 2.63% As indicating that the arsenic and antimony are upgraded (ore composition 10% Sb and 0.78% As). The reagent setup of this test was as follows: activator lead nitrate at 250 g/t, Frother/secondary collector-Aero float at 60 g/t, collector SIBX at 60 g/t, depressant Dextrin at 300 ...

In this sense, froth flotation plays a key role in the recovery of stibnite from both sources. In view of this, a comprehensive review of technical and environmental aspects related to the ...

A typical stibnite deposit may contain the antimony sulfide along with pyrite and a gangue consisting of quartz, calcite, barite, kaolin and gypsum. The ore grading about 2.7% Sb is put to a combined treatment by hand-sorting, heavy medium separation and flotation (Xikuangshan, 1964, Chen, 1964, Huang et al., 1965, Xikuangshan, 1979). First ...

Stibnite Gold Project Plan of Restoration and Operations 10 r5 Once crushing and grinding has reduced the ore to small particles with a large surface area, the next step is flotation: the first flotation circuit is designed to produce antimony rrich concentrate; the second

Stibnite is concentrated and separated from gangue minerals by flotation, using a variety of activators and collectors [[10], [11], [12], [13]]. The use of a metal ion as …

When the ore contains more than 90% stibnite, it can be treated as crude antimony; if it contains 45–60% antimony, it can be extracted by melting because of a …

The ore characteristics are coarser grain size of the stibnite, which is favorable for flotation. But the clay minerals (kaolinite and illite), pyrite and arsenopyrite in the ore will bring some ...

Furthermore, it is worth highlighting the importance of adopting a geometallurgical plan for stibnite-bearing deposits that allows the new (flotation) operations to deal with technical difficulties that might arise from the lack of knowledge about the inherent variability of the Run-of-Mine ore and its effect on process performance …

aspects of froth flotation for a stibnite ore from Xikuangshan and some other locations in China (Hu, 1988; Anderson 2012). On the basis of the aforementioned considerations and to the best of the authors' knowledge, a comprehensive and updated assessment focusing on key aspects of the froth flotation of stibnite ores is still

Stibnite, the antimony sulphide mineral, responds much better to flotation after being activated with lead nitrate. ... A flocculant and dispersant useful in flotation of non-metallic and iron ore along with cationic promoter. Cement Standard cement with variable lime content. Dry .5 to 2.0:

A technology for stibnite and stibnite, which is applied in flotation, solid separation, wet separation, etc., and can solve the problem that ore cannot be efficiently utilized. Pending Publication Date:

The authors report studies into adsorption of tannin and cow-parsnip extract components on stibnite, arsenopyrite and chalcopyrite using UV spectroscopy, scanning laser microscopy and measurement of air bubble detachment from a mineral particle. It is found that tannin and organic reagents are selectively adsorbed on the surface of the …

Bulk flotation followed by sequential flotation of gold-bearing sulfides, and depression of stibnite. This method was practised at the Bradly concentrator (USA) and consisted of the following steps: first, bulk flotation of stibnite and gold bearing sulfides at pH 6.5 using lead nitrate (Sb activator) and xanthate; second, the bulk concentrate is reground in the …

CONDITIONING AND FLOTATION The classifier overflow adjusted to a pH of approximately 7.5 to 7.8 is conditioned with a stibnite activator such as copper sulfate …

Sulfide-ore-bulk flotation followed by selective copper flotation with the addition of arsenic sulfide depressants can also separate copper and arsenic ores via conventional flotation [6].

6.1 Antimony (Stibnite Ore) Antimony deposits and prospects in the form of quartz- stibnite veins and replacement bodies are scattered in the Slate belt between Papun and 15°N. Clegg gives a summary description, based on Heron in Clegg (1944a), of the deposit at Thabyu village (15°35′N, 98°07′E), 70 km southwest of Thanbyuzayat.
