Although China has the largest antimony reserve in the world the over exploitation has led to the depletion of such antimony resource According to the static reserve production ratio adopted by the United Sates Geological Survey USGS the mining life of antimony ore is lower in China years than the global average 11 years
The high antimony slag from this process was reduced in the furnace by coal Antimony recovery reached % after direct reduction with coal Liu et al 2014 Padilla et al 2018 reported the results of a study of Sb 2 S 3 treatment from copper rich concentrate in order to remove Sb as an alternative process to the volatilization of antimony
John Paulson backed Perpetua Resources has agreed to work with Sunshine Silver Mining & Refining Co to find ways within the US to process antimony one of the critical minerals under China s
This paper focuses on the environmental leaching of antimony a critical mineral using deep eutectic solvents Mining residues often contain embedded antimony posing environmental risks Deep eutectic solvents known for being low in toxicity cost effective and environmentally friendly present a promising avenue for sustainable antimony extraction The
400 to roughly 16 companies China is not only the top producer also boasts the majority of antimony but processing facilities 7 somewhat analogous to China s role in REEsproduction 8 Due to its ability and capacity to process a major portion of the world s antimony China s downward trend in mining antimony production has not
3 Perpetua s antimony and gold mine in Idaho In January the Biden administration issued final permitting approval for a combined antimony and gold mine north of Boise Idaho Over the course of the eight year review process Perpetua Resources changed its mine design three times to incorporate feedback from external stakeholders
The production process of antimony ore varies depending on the type of ore For low grade ore the foam flotation method is used to enrich antimony while high grade ore can be melted at 500 600 °C to extract antimony from the gangue fish and algae around the antimony mine and the result show that average concentration of antimony in
Perpetua Resources said on Monday its Idaho unit has signed a non binding agreement with private firm Sunshine Silver Mining & Refining to explore the processing of antimony amid a brewing trade war between the US and China over critical minerals Shares of Perpetua rose % in premarket trade
Perpetua and United States Antimony take first step into connecting links in Idaho and Montana United States Antimony Corp and Perpetua Resources Corp companies at the vanguard of breaking America s heavy reliance on imports for antimony are investigating the potential of integrating their expertise to establish an antimony supply chain in
Antimony oxide ore beneficiation has become one of the world s largest mineral processing conundrums In recent years many experimental studies dealing with antimony oxide ore have been carried out resulting in new technical achievements Much attention has been paid to improving the mineral processing technology of antimony oxide based on such experiments
Due to increased antimony bearing mineral mining/processing over the past few decades there has been increased deposition of antimony into the environment Selim 2012 The anthropogenic sources stated earlier contribute to a significant portion of the pollution

1 Introduction Antimony is a toxic trace element of increasing concern due to its wide distribution in the environment Antimony has no known biological function Filella et al 2002 and can cause serious adverse effects to living organisms above certain threshold concentrations Kabata Pendias and Mukherjee 2007 It can inhibit culturable soil bacteria and
2 Antimony is a non renewable strategic mineral resource and an indispensable and important raw material for modern industrial development With the high intensity resource mining in recent years the consumption of antimony resources is too large Antimony beneficiation methods are important to improve the recovery rate of antimony ore
The removal of antimony from wastewater using traditional methods such as adsorption and membrane filtration generates large amounts of antimony containing hazardous wastes posing significant environmental threats This study proposed a new treatment strategy to reductively remove and recover antimony from wastewater using an advanced UV/sulfite
While Mandalay Resources TSX MND Costerfield mine in Victoria is currently Australia s only antimony producer Larvotto owns the Hillgrove Project in New South Wales According to a Prefeasibility Study released in August Hillgrove is expected to produce 41 000 ounces of gold and 5 400 tonnes of antimony annually over the course of its seven year life delivering

According to the static reserve production ratio adopted by the United Sates Geological Survey USGS the mining life of antimony ore is lower in China years than the global average 11 years The rapid economic development has induced the continuous growth of demand for antimony which may aggravate the depletion of antimony resources
Antimony Sb is a toxic and carcinogenic heavy metal and main group V with an atomic weight of in periodic table element Johnston et al 2020 and its outer orbital electron configuration is s 2 p Sb is considered to be the primary pollutant of both the United States and European Union Montserrat et al 2002 Sb usually exists in environments
Antimony Sb is a harmful element and Sb pollution is one of the typical environmental issues in China meaning that understanding of the geochemical behaviors of Sb is the key to control the fate of environmental Sb pollution Sb tends to migrate in soluble form in the water sediment system but the fate of dissolved Sb is poorly known Duliujiang river basin
