Amalgamation and Small-Scale Gold Mining at Ancient Sardis

Gold mining in western Turkey goes back to ~3000 BC and alluvial gold was mined from Astrya approximately 25 km from ancient Troy &(Bayburtoğlu Yildirim, 2010). At Sardis, alluvial gold mining dates to ~700 BC and gold is still produced today. How-ever, owing to the small size of the gold at Sardis, it was necessary to use mercury to

A Rising Gold Mining Industry in Turkey

17/07/2015 Statistics seem to back this up too as Turkey has gone from producing very little gold by commercial operations in the year 2000 to producing 31 tons of gold in 2014; that figure makes them the largest gold production country in the Middle East by far. Prior to that, most of the gold production was coming from small-scale artisanal mining, and did not account for any considerable (or recorded)

Artisanal and small-scale gold mining OECD

One of the main areas of OECD's work in the responsible sourcing of minerals is to ensure that international standards do not further marginalise workers of the informal sector. This implies working on the formalisation of Artisanal and Small-Scale Mining (ASM). ASM is a major source of mineral resources production in the world. It is largely informal, and is associated with low levels of safety

Report on Small-scale Mining in Papua New Guinea

scale Mining Small-scale mining in PNG probably started as early as 1888 when gold was first found in quantities on Sudest Island in the east. This was followed by discoveries in other parts of the country. This was followed by a gold rush in the Wau and Bulolo districts where payable gold was found at Koranga Creek in 1922. The gold rush developed into a major dredging operation

The Mercury Problem in Artisanal and Small‐Scale Gold

Mercury‐dependent artisanal and small‐scale gold mining (ASGM) is the largest source of mercury pollution on Earth. In this practice, elemental mercury is used to extract gold from ore as an amalgam. The amalgam is typically isolated by hand and then heated—often with a torch or over a stove—to distill the mercury and isolate the gold.

The Resiliency of the Philippine Small-Scale Mining

Artisanal and small-scale gold mining boosts rural programs and infrastructure development in the Philippines. ASGM is a main source of income for rural communities in the Philippines and has been a catalyst for social and economic progress where it operates, such as the small town of Buenavista, Quezon, home to around 30,000 people. This article from the planetGOLD Philippines team examines

mining in Ghana: identifying problems and possible solutions

environmental problems encountered in small-scale gold-mining regions today. Pollution from mercury Although small-scale gold-mining activity is respon-sible for triggering a number of often irreversible erosional and siltation processes, it is a now widely recognized fact that the most serious environ-mental problem in the industry is excessive mercury

Artisanal and Small-Scale Gold Mining Without Mercury

Although many miners use mercury in artisanal and small-scale gold mining, it is possible to safely and economically recover gold without it. Mercury-free techniques are safer for miners, their families and local communities. They may also help miners market their gold at higher prices. Many artisanal and small-scale miners are achieving high rates of gold recovery without mercury, benefiting

Artisanal and Small-Scale Mining World Bank

Artisanal and small-scale production supply accounts for 80% of global sapphire, 20% of gold mining and up to 20% of diamond mining. It is widespread in developing countries in Africa, Asia, Oceania, and Central and South America. Though the informal nature and on the whole un-mechanized operation generally results in low productivity, the sector represents an important livelihood and income

How “Small” Is Small-Scale Gold Mining?

In small-scale mining gold ore is given the top preference for its effectiveness in generating revenue promptly. The extracting techniques vary: from rudimentary with the use of minimum equipment and involve intense physical labor to highly mechanized. Most of the time small-scale mining takes place at the surface of the riverbed alluvium deposits, where the rock is mostly unconsolidated, but

Majority of small-scale miners need mechanisation

The small-scale mining sector has become the dominant gold producer in the country after overtaking established mining companies in the last few years. Latest data from Fidelity Printers and

The Mercury Problem in Artisanal and Small‐Scale Gold

Mercury‐based artisanal and small‐scale gold mining (ASGM) causes more mercury pollution than any other human activity. 1 In this practice, mercury metal is used to extract gold from ore as a stable amalgam. The amalgam is then heated to evaporate the mercury and isolate the gold. While mercury amalgamation has been used for thousands of years to mine gold and silver, 2 it is unfortunately

Gender Issues in the Artisanal and Small-Scale Mining

26/05/2020 Artisanal and small-scale mining (ASM) is a significant source of income for tens of millions of people in developing countries. ASM refers to small groups and individuals engaged in low-cost and laborintensive excavation of minerals using minimal mechanization. ASM techniques are used in the production of precious minerals such as gold and diamonds, fertilizers used in agriculture, garnet

Relatively less is known about Zambia’s Artisanal Small-Scale Mining (ASM) sector. In contrast to the firms dominating the copper extraction sector, the ASM sector is mostly done on a small scale, locally driven, has low barriers to entry, and involves different types of minerals beyond copper. It, however, represents an important and growing part of the mining industry in Zambia. The ASM
