Small-scale miners urged to embrace GoldKacha technology to avoid environmental pollution

 For a sustainable mining of gold and other natural resourc­es, small-scale miners have been urged to adopt the mercu­ry-free rock processing technology, known as GoldKacha, to mitigate the negative environmental impacts associated with traditional mining methods.

The call comes as illegal mining activities have begun to take a toll on the environment, posing risks to both citizens and ecosystems.

The GoldKacha technology, introduced and endorsed by the government, stands as a secure solution to environmental degrada­tion caused by illegal miners.

Launched by President Nana Addo Dankwa Akufo-Addo last year, the mercury-free mining equipment, developed by Commod­ity Monitor Limited, a Ghanaian commodity trading logistics and research company, has proven to be both viable and environmentally friendly.

Speaking at a stakeholders’ work­shop in Tarkwa, the Chief Exec­utive Officer of the Commodity Monitor Limited, Stephen Yeboah, emphasised the positive impact of GoldKacha on responsible small-scale mining.

The workshop was organised for artisanal small-scale miners (ASM) as critical stakeholder across all mining districts to facilitate a multi-sectorial and interdisciplinary discourse, dialogue and sharing of ideas.

The interactions focused on how the artisanal mining operators can be provided with the necessary financial and technical assistance to adopt efficient and clean mining technologies that will not only improve gold productivity but also minimise or at best eradicate the negative environmental impact of their activities.

The participants discussed the health impact of chemicals used in gold recovery, the efficiency of mercury-free gold processing technology, and its functions and addressing the negative environ­mental as well as health effects of small-scale mining operations across the country.

Mr Yeboah highlighted the unprecedented environmental and social problems caused by some small-scale and illegal miners, leading to soil degradation and the destruction of cocoa and other arable farms.

The pollution of rivers and water bodies, essential sources of drinking water, due to the uncontrolled use of mercury, cyanide, and other chemicals, prompted the introduc­tion of GoldKacha as a solution.

The mercury-free machine has the capacity to recover a minimum of 90 per cent of gold gravity recoverable without the use of harmful chemicals, in contrast to traditional methods recovering less than 20 per cent of the ore content.

Ghana, as a signatory to the Minamata Convention aimed at eliminating mercury use in mining, sees GoldKacha as a critical tool for implementing the convention’s principles.

Mr Yeboah emphasised the importance of prioritising human health, stating that the mercury-free technology is crucial for safeguard­ing the environment, project all and well-being of individuals who might be exposed to contaminated environments.

The gold mining sector has long been a major contributor to Gha­na’s economy, remaining the highest export earner with US$6.6 billion in export earnings in 2022.

The artisanal and small-scale gold mining (ASGM) sector’s contribu­tions to the national gold produc­tion have steadily increased from 2.2 per cent to 43 per cent between 1989 and 2021.

Prof. Paul Poku Sampane Osei, Head of Forensic Unit at the Kwame Nkrumah University of Science and Technology (KNUST), stressed on the harmful effects of using mercury, uranium, and cya­nide in gold extraction.

These toxic chemicals pose seri­ous health risks, including damage to the liver, kidney, maternal health, cancer, and malformation in unborn children.

He urged miners to embrace mercury-free technology and mine responsibly, emphasising the need for collective efforts to raise aware­ness about the health effects of toxic chemicals.

Municipal Chief Executive Offi­cer for Tarkwa Nsuaem, Benjamin Kessie, echoed the importance of exploring improved technology for sustainable and responsible mining practices, emphasizing its potential as a game-changer in the field.
