Global Mercury Project
Removal of Barriers to the Introduction of Cleaner Artisanal Gold Mining and Extraction Technologies.
Facts
and figures
An estimated 1,000 tonnes of mercury are released annually into
the environment from informal or small scale gold mining, accounting
for between 30-40% of man made mercury pollution. (Mercury is
naturally released into the environment from the weathering of
rocks).
Due to inefficient processing techniques as much as 2g of mercury
can be released into the environment for every gram of gold recovered.
This is of grave ecological significance as most artisanal mining
takes place within river basins which cross international boundaries.
It is estimated that the Amazon basin receives 40 tons of mercury
a year in this way while mining in Indonesia adds 150 tons to
the Java Sea.
Mercury contamination is persistent, rapidly absorbed by aquatic
organisms and is biomagnified as it passes up the food chain - miners
and their families are advised not to eat local fish, particularly
carnivorous fish.
As well as mercury contamination, artisanal mining's ecological
impacts include diversion of rivers, water siltation, landscape
degradation, deforestation and habitat destruction.
The current number of people working in artisanal and small-scale
gold mining, according to recent UNIDO estimates, is between
10 and 15 million in more than 55 countries, usually in Africa,
Asia and Latin America. The number of women and children directly
employed in artisanal gold mining may be as much as 4.5 million
and 300,000 respectively, although many more are affected by
mercury contamination of their local environment. Altogether
between 80 and 100 million people worldwide may be dependent
on artisanal mining for their livelihood.
Unfortunately, miners are seldom aware of or, driven by poverty,
are forced to ignore the health risks of mercury which they ingest
through their work, and through polluted water and food in their
environment. |
Project
description
The Global Mercury Project aims to raise awareness of health,
economic and environmental risks among miners and their communities,
promote the use of cleaner extraction technologies, make health
assessments and provide health solutions for victims of mercury
poisoning, especially children who are particularly vulnerable
to neurological damage.
The new safer technologies being demonstrated by the project
are more efficient, and cheap to introduce. GMP recognizes
that poverty is the root cause of the miners' unsafe practices
and a long-term solution must be a social and economic one.
GMP also works to develop regulatory mechanisms and government
capacities, conducts health and environmental assessments and
builds monitoring capacities in local laboratories. Recognising
that miners do not often control their own operations the project
also seeks to engage the 'middle men' who buy the miners' gold,
own processing equipment and supply mercury to the miners.
Poor health and sanitation facilities, lack of schools and
other facilities in remote mining camps is another problem
and the GMP programme tackles other health and social issues - such
as HIV /AIDS and malaria - in its multi-faceted approach. |
SELECTED PROJECT ACTIVITIES/RESULTS
- Awareness of mercury dangers has reached at least 10,000 people
in all project countries. The project has used mobile demonstration
units (TDUs) to demonstrate methods to improve gold recovery and
reduce mercury use, has investigated mercury poisoning and worked
on other health problems related to artisanal mining communities
such as malaria, sanitation, HIV/AIDS and TB.
- The EU has legislated to ban mercury trade from Europe from 2011.
- Better and simple techniques introduced by GMP can easily double
gold recovery and increase income. Fair Trade initiatives, which
eliminate middlemen, encourage better practices and secures premium
for miners and communities, have also been supported by the GMP.
- By creating more income for miners and making their communities
more stable and less migratory GMP has helped reduce child labor
and allow better primary education. In the mining village of Crepurizão,
Brazil which more than 700 children are being educated by local teachers
in a school funded by miners. A primary school for boys and girls
in Gugub, Sudan, another GMP project site, is also funded largely
by the profits from gold mining.
- New legislation on mercury has been proposed for incorporation
into the Mining Codes of the six GMP project countries. Countries
like Zimbabwe, Tanzania, Indonesia and Laos are introducing GMP’s
suggestion of banning whole ore amalgamation processes.
- GMP’s approach has been replicated in countries such as Mozambique,
Venezuela, Guinea, Ecuador, Cambodia and Senegal, which neighbour
GMP countries. These projects have implemented either by the GMP
team, or by other institutions using materials and approaches developed
by GMP.
- GMP’s awareness campaign has a strong focus on promoting
prevention procedures to HIV/AIDS and tropical diseases such as malaria.
GMP uses nurses to communicate the problems related to immune systems
and mercury exposure to risk groups, especially women. GMP is also
promoting the use of simple sand filters to produce clean drinking
water. It has also installed water filters in mining communities
and taught miners how to build water wells and ventilated latrines.
- The project conducted extensive field research into different methods
of gold extraction technologies and socio-economic studies of mining
communities.
- Health and environment surveys of mining sites showed widespread
symptoms of mercury poisoning – at one site in Brazil almost
50% of miners showed the intentional tremor, a typical signs of mercury
damage to the central nervous system. Symptoms of mercury intoxication
were shown by 70% of miners and 69% of child miners at a site in
Zimbabwe. High concentrations of mercury are found in the breast
milk of mothers from mining communities.
- The results of surveys are given to communities at training sessions,
when health and environmental advice is provided, alongside the demonstration
of extraction technologies.
Community
- GMP also promotes income-generating activities to communities.
The activities are designed to provide a more sustainable livelihood
than mining and include: making tropical seed jewelry, aquaculture
and reforestation work.
Training
- About 200 trainers have been trained in the GMP countries. They
will train other trainers and disseminate the concepts of cleaner
technologies and mercury pollution awareness throughout the mining
communities.
- Assessments of previous initiatives to introduce new technologies
and practices to miners have shown that the biggest barrier is educational.
Since gold mining communities are migratory and scattered over large,
often remote, areas GMP has pioneered the use of mobile training
facilities (transportable demonstration units or TDUs) which are
now used by all the project’s participating countries.
- The units, housed in a tent, school or other building at a mine
site or nearby population centre, demonstrate a variety technical
options to the miners who can then select the most appropriate choice
for their needs.
- Miners’ training can be extended to geological exploration,
ore reserve estimation, mining and concentration techniques, water
reclamation, book-keeping and other skills. Economic and social welfare
can be improved with advice on obtaining legal mineral titles and
financial support, planning mining operations, starting alternative
economic activities, community and family advice.
- The training modules – outlined in a series of international
workshops in 2005 to prepare for the TDU activities consist of: i)
how to produce more gold; ii) how mercury makes us sick; iii) how
to use and re-use mercury safely; iv) how to make more money; v)
how to protect water supplies and improve sanitation; vi) how to
prevent malaria HIV/AIDS and other diseases.
- TDU activities are advanced in all countries. In Zimbabwe TDU visits
have been planned for 15 separate communities; in Brazil the arrival
of the TDUs has been promoted by brochures, posters, T-shirts and
CD distribution; training in TDU management is taking place in Indonesia
and in Laos; and special educational materials in Arabic have been
distributed in Sudan.
- At the same time areas and communities have been receiving the
results of their health assessments and nurses and public health
workers are being trained in mercury poisoning assessment and rehabilitation.

Legal
GMP's policy group is working with country governments to develop policies
and legislation that address the hazards of mercury in mining. In 2005
it helped Zimbabwe draft new regulations. In a landmark decision the
European Union (2005) has called for global phase-out of mercury trading
by 2011 although the phase-out of mercury trading in Europe and North
America (with China the biggest exporters) has made developing countries
the primary destination for mercury trading.
Women and children
Although only men are generally involved in ore extraction, women often
help in processing operations. Since most young children accompany their
mothers while working they are exposed to (if not also involved in) panning
and processing activities. They are also exposed to mercury though contaminated
water and food (especially fish) because of mercury's persistence in
the food chain. The damaging effects of mercury poisoning are particularly
severe in children.
Women working in mining were trageted at the Tanzania Women Miners Association
Conference (2004).
