Welcome to Atom Minerals tailings reprocessing specialists developing stranded mineral assets underpinned by strong technical business case methodology ABOUT US Our Ethos Director Profiles The Victorian gold rush from 1851 to 1896 produced over 61 million ounces of gold In those days head grades were high and recoveries were low by
Mine tailings the byproduct of mining and mineral processing are increasingly mass produced as a result of increased demand for metals and minerals as well as the advancement in technology that allows for the exploitation of lower grade ores Lower grades can increase the volume of tailings that may contain new gangue minerals that should be evaluated
Similarly tailings dumps arising from the processing of chrome ore in the Lower Group reefs of the BC are also being retreated to recover PGEs Several commercially profitable enterprises have also been set up with the sole intention of retreating tailings dumps arising from South Africa s Witwatersrand gold processing operations
The tailings reprocessing project at Barrick s end of life Golden Sunlight Mine was officially opened in a ribbon cutting ceremony attended by Montana Governor Gianforte Barrick President and Chief Executive Mark Bristow representatives of the Montana federal congressional delegation and members of the community
The announcement comes after the company said earlier this year that results of Phase 1 of the Hellyer Tailings Reprocessing Project at the Hellyer Gold Mine Tasmania Australia are expected in early 2023 and will be a key milestone to deploying a full scale pilot program as a precursor to plant engineering and construction there
1911 Gold TSXV AUMB; OTC AUMBF has begun tailings reprocessing operations at the True North complex at Bissett Man where it expects to process between 170 000 and 190 000 tonnes of historical tailings this year to recover approximately 3 500 to 4 000 oz of Early in 2022 the company completed a sampling program to characterize the
Millions of tons of solid waste are generated by artisanal and small scale gold mining in several regions of the world This study focused on the tailings from the Abu Hamad artisanal gold mine located in northeastern Sudan The results of the analyses carried out showed that this amalgam waste contained on average g/ton of gold 50 g/ton of mercury g/ton
The reprocessing of tailings presents an opportunity via modern technologies for low cost recovery of gold Such activities can be used to supplement revenue for existing operations Reprocessing tailings for gold recovery can be complex and is dependent on the mineralogy of the dump which is in turn
In gold copper sulfide and iron ore tailings there s potential to extract further minerals and mining companies are now figuring out ways to bring out valuable minerals and metals from tailings A standard method of reprocessing involves dragging tailings from an existing dam back to the concentrator and using selected mineral
Incentivization of Tailings Reprocessing Governments should support environmentally friendly processing plants for reprocessing tailings Ensure proper monitoring of operations Map and survey ASGM tailings to identify potential for secondary mineral extraction Provide training to ASGM operators for extracting valuable materials from gold
This study explores the use of secondary gold tailings SGTs in concrete production to solve sand sustainability issues This approach addresses waste issues and presents a sustainable material alternative to conventional sand investigating different SGT proportions ranging from 0% to 100% to replace fine aggregate in structural concrete This

Either way sustainable re handling and reprocessing of tailings is becoming a more prominent part of mining operations Tailings management requires a careful approach and integrated solutions All aspects relating to de risking re handling water management and reprocessing need to be considered in a sustainable way
There are mainly several methods of gold tailings reprocessing 1 The iron recovery from gold tailings can adopts common processing technology such as gravity separation magnetic separation flotation roasting magnetic separation and their combined processing technology There are only four kinds of valuable minerals recovering by magnetic
Our recent research in collaboration with the International Institute for Sustainable Development and Intergovernmental Forum on Mining highlights the critical importance of managing tailings in artisanal and small scale gold mining ASGM ASGM is responsible for up to 20% of the world s gold supply employing over 20 million people globally
An IGF report outlining technical aspects of artisanal and small scale gold mining ASGM examining existing governance frameworks and providing recommendations for policy makers to improve awareness education safety and regulation of ASGM tailings
The project involves the reprocessing of ground rock known as tailings from which gold was previously extracted in the Golden Sunlight mills The focus will be on removing and concentrating sulfur iron pyrite that will then be sold to and used in gold production by Nevada Gold Mines NGM the largest gold producing complex in the world
In gold copper sulfide and iron ore tailings the potential of extracting minerals is an opportunity Reprocessing tailings to collect the valuable minerals can be a cost effective approach
1911 Gold is a junior explorer that holds a highly prospective consolidated land package totalling 55 500 hectares within and adjacent to the Archean Rice Lake greenstone belt in Manitoba and also owns the True North mine and mill complex at Bissett Manitoba where it is reprocessing historic tailings on a seasonal basis 1911 Gold believes
South Africa is unlikely to regain top slot as the world s biggest gold producer but there are still decades of gold production in the future from deeper mines and the reprocessing of historic mine tailings Additionally the higher gold price especially in rand per kilogram terms makes previously marginal resources economic once again
