Delve is a global platform for artisanal and small-scale mining (ASM) data. Its vision is a world in which ASM is recognized as an important contributor to global …
Artisanal and small-scale mining (ASM) activities have contributed, in most cases, to the rural development of some African countries. Practically, these activities have influenced the environmental, health and socio-economic status. In essence, there is a need to investigate how these activities fuel poverty eradication in Africa. Here, a …
It initiated a chain of events that further diminished interest in and depreciated the value of the country's diamonds, depriving small-scale diamond miners of viable sources of sponsorship ...
Washington Declaration on Integrating Development of Artisanal and Small Scale Diamond Mining with Kimberley Process Implementation 129.69 KB
If you want to conduct mining operations you need to obtain a mining permit from the Department of Mineral Resources and Energy (DMRE). No person is allowed to mine without a mining permit. Mining permits are not transferable. They are aimed at controlling prospecting and mining, having regard to considerations for health and safety ...
Small-scale mining refers to operations where individuals or small enterprises employ workers who use traditional mining methods with little or no mechanization. On the other hand, large-scale mining utilizes simple to sophisticated mining technology and machinery to mine and process ore.
The study aimed at finding out the impacts of Artisanal Small-scale Mining (ASM) on livelihoods in northern Malawi- Mzimba district. It also examines the Malawian mining policies and their implications on ASM. …
In Angola, although mining is carried out by large and medium scale companies, Artisanal and Small Scale Mining (ASM) is significant. The ASM sector produces diamond, gold and dimension stones. Angola is the third largest producer of diamonds in Africa. Hydrocarbons (oil) however, completely dominate the country's economy and extractive …
Artisanal and small-scale mining and the sale of diamonds is permitted in Kimberley Process-designated compliant zone subprefectures, which include Berberati, Boda, Carnot, Gadzi, and Nola.
Artisanal and small-scale mining often occurs near large corporate mining concessions. This proximity can add to the complexity of community engagement. Artisanal mining standards help empower artisanal miners to engage with large-scale miners in order to deter social conflict.
The country's diamond production fell from 15.56 million carats in 2004 to 9.66 million carats in 2022, according to Kimberley Process data. While no new major …

Artisanal and small-scale mining (ASM), which refers to mining with minimal or no mechanization often in the informal sector, has increasingly captured the interest of governments, international organizations, and private corporations because of its growing role in national economies and its …
This research demonstrates how the application of a novel methodology that relies on traditional and low-cost geophysical methods can contribute to mine planning in small-scale mining. A combination of resistivity and …
In the late 1980s, the government allowed the small-scale miners to work areas along the 40-mile diamond-bearing stretch of the Birim River, an area unsuitable for mechanized mining.
Small to medium scale mining equipment for the recovery of gold, chrome, tin, tantalite and more. We are based in South Africa, but our mineral processing plants are supplied globally.
MARINE MINING. Marine mining involves extracting diamonds from the seabed, deep under water. Ships with specialised technology are used to mine for diamonds deep out at sea by using a powerful crawler that sucks gravel on the seabed up through flexible hoses or pipes. In the earlier days of marine mining, a swimmer would collect diamond …
While rough diamond production has traditionally been dominated by a handful of industrialized mining companies, the Kimberley Process (KP) has focused predominantly on the impacts upon and the impacts of artisanal and small-scale mining (ASM).
However, the application of traditional thinking and definitions of small-scale mining to a European context is problematic, such that the evolution of modern smaller scale mining also requires re-thinking of the underpinning concepts. We discuss various company structures, scales of mining and their specific features.
