Other antimony removal or control technologies such as zero discharge, recycle, water reuse, process stream segregation, and solar evaporation are often feasible in individual mining wastewater situations.
Gold CIL (Carbon in Leach) Process is an efficient design of extracting and recovering gold from its ore. By cyaniding and carbon leaching crushed gold ore slurry simultaneously, CIL process lower the gold mining operation cost and increase gold recovery rate to a degree of 99%.

Closed Gold Mine. Water from a closed gold mine in Montana was also tested in CESR-process bench tests. In reducing the sulfate concentration to approximately 30 mg/L, the total dissolved solids (TDS) concentration of this water was reduced from approximately 4400 mg/L to 1400 mg/L (Table 2).
Water quality in the historical Stibnite Mining District has been impacted by more than a century of mining activity, most of which took place before modern environmental regulations existed.
The chemical behaviour of antimony is as complex as that of arsenic, its neighbour in the periodic table (Wiberg, 1985). It is speculated that antimony could be a natural co-contaminant with arsenic in some drinking-waters (Gebel, 1999b). Soluble forms of antimony (and arsenic) tend to be quite mobile in water, whereas less soluble species
Water samples from Xikuangshan (China), the world largest antimony (Sb) mine with a Sb mining and smelting history of more than 200 years, were analyzed. These water samples ranged from stream water in the vicinity of the mining and smelting area that received seepage from ore residues to the underground mine-pit drainage.
Room temperature extraction on e-waste plastics obtained lower extraction efficiencies, yet longer incubation durations lead to higher yields. In conclusion, the main challenge associated with antimony mining from plastic waste could be its heterogeneous composition; therefore, the development of reference analytical procedures is highly needed.
Coexisting arsenic (As) and antimony (Sb) in mining wastewater is a common and great concern. On-site simultaneous removal of As and Sb from mining wastewater was achieved by using a reusable granular TiO 2 column in this study. To evaluate the accuracy of the scale-up procedure, As and Sb adsorption from wastewater was studied in both large (600 g TiO 2) and small columns (12 g TiO 2) …
Antimony is a chemical element with the symbol Sb (from Latin: stibium) and atomic number 51. A lustrous gray metalloid, it is found in nature mainly as the sulfide mineral stibnite (Sb 2 S 3). Antimony compounds have been known since ancient times and were powdered for use as medicine and cosmetics, often known by the Arabic name, kohl.

Sep 01, 2019· In this study, a combined process of alkaline pressure oxidative leaching (APOL) and Na 2 S leaching was proposed to extract arsenic and antimony from high arsenic smelter ash. The arsenic was selectively dissolved into the leachate during APOL, while the antimony was separated into the residue as insoluble NaSb(OH) 6.The effects of different process parameters on the extraction of …
Mineralization and historical mining of stibnite (antimony sulfide), tungsten, gold, silver, and mercury in the headwaters of the East Fork of the South Fork Salmon River (EFSFSR) near the former town of Stibnite in central Idaho resulted in water-quality impairments related to mercury, antimony, and arsenic. Additionally, mining-related disturbances and wildfires have resulted in a lack of ...
Follow a side track off the Queen Charlotte walking Track to explore the Antimony mining era. Antimony is a lead-grey ore often found in quartz rock. It was used to make pewter, ammunition and print type, and is still used in lead-acid batteries and solder. Ore containing antimony was discovered in the area in 1873.
The natural sulfide of antimony was known and used in Biblical times as medicine and as a cosmetic. Antimony in its elemental form is a silvery white, brittle crystalline solid that exhibits poor electrical and heat conductivity properties. Commercial forms of antimony are generally ingots, broken pieces, granules, and cast cake.
7.3.2 Effects of mining on water quality The type of water contamination produced by a mining operation depends to a large extent on the nature of the mineralization and on the processing chemicals used to extract or concentrate minerals from the host rock. The water contaminants of most concern are summarized in the Table 7.1.
It is found that iron oxides prepared by chemical methods present superior adsorption ability for Sb(III) and Sb(V). However, this process is more costly and iron oxide activity can be inhibited by plenty of sulfate in antimony mine drainage.
Human exposure to antimony can take place by breathing air, drinking water and eating foods that contain it, but also by skin contact with soil, water and other substances that contain it. Breathing in antimony that is bound to hydrogen in the gaseous phase, is what mainly causes the health effects.
The problem discussed in this antimony process study is limited to a concentrator capable of beneficiating 150 tons per day of antimony ore.The antimony in this study occurs as the mineral stibnite (Sb2S3) in association with small amounts of pyrite, arsenopyrite, galena and lead sulfantimonides. The gangue is composed largely of quartz but contains, in addition, a small amount of talc.

Public health effects of antimony. The Agency for Toxic Substances and Disease Registry has composed a comprehensive account of the public health effects of antimony, including health effects by route of exposure (inhalation, oral, and dermal exposure), toxicokinetics (absorption, distribution, metabolism, and excretion), biomarkers of exposure, and effect, among other chapters.

However, if …
For example, two relevant treatment systems were recently installed to remove arsenic and antimony from drinking water in Alta, Utah. One system uses a CF process to remove primarily arsenic, while the other system uses AM to remove arsenic and antimony. Both systems were designed and installed by Pureflow Filtration.
Antimony is sometimes found in pure form. It is also obtained from the mineral stibnite (antimony sulfide) and commonly is a by-product of lead-zinc-silver mining. Other antimony-bearing minerals include sibiconite, tetrahedrite and ullmannite. It is mined in China, Bolivia, South Africa and Mexico.
