Unregistered small-scale miners are those who engage in mining extractions and/or processing ores without having a mining license to operate and they often work on mineral concessions owned by large-scale mining companies without their permission, on people's land, and in areas prohibited for mining (Amankwah and Anim-Sackey, 2003).
The mining industry in Zimbabwe is divided into small scale and large scale mining schemes. Large scale schemes are run by multi-national co-operations and are up to date with modern mining systems. However, with the vast spread of Zimbabwe mineral resources, small scale mines are sprucing up everywhere in the country's mineral rich belts.
Our research has shown that small-scale mining will enable access to the many small and complex critical metal deposits of European geology. However, a set of preconditions are …

The Bitmain Antminer D9 is a popular crypto mining machine with an X11 mining algorithm, meaning it can mine popular coins like DASH. The D9 has a hash rate of 1770 gigahashes per second and a relatively low power consumption of 2839 watts, making it more affordable to run than many other top mining machines.
Over the past two decades, a sizable body of literature (e.g. Maconachie and Binns, 2007, Hilson, 2009, Pijpers, 2014) has emerged that draws attention to the links between subsistence farming and artisanal and small-scale mining (ASM) – low-tech, labor-intensive mineral extraction and processing – in sub-Saharan Africa.The consensus among scholars who have contributed to …
Cyanide leaching is in a process of auto-diffusion in many small gold mining areas. It is most important to start now with education of the miners to guide them from the beginning.
A version of this small-scale mining persists—known today as artisanal mining—but new research shows it is having a growing and sometimes devastating effect on the environment. Researchers from NASA, U.S. universities, and government agencies in Ghana recently used satellite data to estimate the extent of vegetation lost to artisanal mining ...

This activity is not always carried out by large-scale companies or industrial machinery; being called small-scale or artisanal mining. Small-scale mining (SSM) was first defined by the United Nations (UN) as: "Any single mining operation that has an annual raw material production of 50,000 metric tonnes or less, measured at the mine entrance ...
of artisanal mining, is often ignored. A team of researchers is exploring women's livelihoods in the artisanal and small-scale mining of 3Ts (tin, and socially benefit from working in tantalum, tungsten), and gold within the Democratic Republic of Congo, needs and providing them Rwanda, and Uganda.
Artisanal and small-scale mining (ASM) provides an important source of livelihood for rural communities throughout the world. These activities are frequently accompanied by extensive environmental ...
Since the beginning of the 21st century, the gold mining industry in Guinea has expanded immensely, from small-scale artisanal to industrial operations. 1 Industrial mining has been largely stimulated by significant foreign investment, made possible by successive reforms of the Mining Code, the latest dating from 2011 and amended in 2013, initiated under the aegis of …
Focusing his presentation on three recent papers and Mining and the Sustainable Development Goals, Prof. Hilson introduced the understanding of ASM as the low-tech labour-intensive extraction of easily accessible deposits.
A Small-Scale Mining Board has been set up as a point of delivery for the services required by the small- scale mining sector. It co-ordinates a substantial amount of expert capacity and experience and specialises in planning and developing a viable mining project through the pre-feasibility stages. The contribution of each board member is ...

In Colombia, two main small-scale and artisanal gold mining activities are underground mining of veins and alluvial mining that is of secondary deposits, i.e. gold particles that tend to concentrate in water channels, giving rise to "placeres auríferos" (Bustamante et al., 2016; Rettberg and Ortiz-Riomalo, 2016).Small-scale placer land mining uses machinery and …
The "Pioneer 15 Shaker" is the only small production, flexible discharge, hydraulic machine on the market. It is easily portable and was designed and manufactured for a small production or pilot processing operation, particularly for the gold mining industry. It will process 8-15 yards per hour, depending on the material.
small-scale renewable energy projects. These are projects with capacities ranging from 1MW to 5 MW. However, the capital costs remain a concern. Access to funding is still a major concern in the sector with the majority still experiencing difficulties obtaining funding. More so, the nature of small-scale mining activities does not allow
Small-scale quarrying and mining operations. Landscaping and excavation projects. ... This machine was eventually used all over the country to build roads while serving the main purpose of replacing manual and costly labor teams of men with hammers, with machines that do the job faster, and at a significantly lower cost. Since then, portable ...
In this way, "small-scale mining is any single unit mining operation having an annual production of unprocessed material of 50, 000 tonnes, or less as measured at the entrance of the mine" (Dreschler, 2001). Small-scale mining could be amenable to …

The idea that artisanal and small-scale mining (ASM) is actually not small is the theme of a recent commentary in The Lancet Respiratory Medicine (Burki, 2019). It cites commonly reported global estimates of 40 million people in 80 countries (IISD, 2017 ), as compared to the approximately 7 million people in "industrial mining."
The literature about SSM in the Global North is limited to research of: 'modern small-scale mining' in medium income nations in Europe (Moore et al., 2021; Sidorenko et al., 2020; Sydd et al., 2022, 2023); technological innovations for mechanically separating fine gold from Yukon ores (Clarkson, 1994); how technology might be diffused in the Global South (Clarkson …
