The United Mineworkers Union of Zambia (UMUZ) has warned that several small-scale mining companies are on the brink of shutting down operations as a result of the ongoing sulphuric acid shortage, which has been exacerbated by continued exports. The small-scale mining sector is currently facing a significant challenge due to the scarcity of sulphuric acid, a critical reagent needed for processing copper ore using leaching methods.

Speaking in an interview with the Zambian Business Times – ZBT, UMUZ President Yosam Nyirongo, bemoaned that despite the existence of local acid production, majority of this acid is being exported, leaving the domestic market underserved. He told ZBT that recent reports also indicate that some companies are on the verge of shutting down operations because of the persistent acid shortage.

Nyirongo argued that the government should prioritize local demand and impose an immediate ban on acid exports until domestic needs are fully met. “We should only consider exporting acid after satisfying the local market,” one industry representative stated. “If local miners have adequate access to acid and can process ore efficiently, the country can realize its targeted copper production.”

 He said large-scale mining firms such as Chambishi Copper Smelter (CCS), Mopani, and KCM are currently producing sulphuric acid as a byproduct of smelting, using environmentally friendly methods that convert sulphur dioxide emissions into acid.

While these large firms generate acid, smaller mines depend on its availability to process ore from dump sites and tailings. He, however, said the ongoing acid shortage threatens the sustainability of small-scale mining operations, which are vital to the economy and support many families.

 Nyirongo said prolonged scarcity could result in the closure of these businesses, leading to significant job losses and reduced government revenues. “Sulphuric acid is essential in ore processing, especially for small-scale miners who use leaching methods.

Larger mines, such as Chambishi Copper Smelter (CCS), Mopani, and KCM, actually produce acid as a byproduct of smelting, using environmentally-friendly technology to convert sulphur dioxide emissions into acid. Small mines, however, depend on this acid to treat ore and mine dump tailings, without it, processing grinds to a halt.”

“If this shortage continues, the consequences will be severe. Small-scale miners, who form the backbone of our economy and support many families, face closure. This means job losses, increased unemployment, and a loss of vital government revenue. It could also drive away foreign investment, further harming the nation’s economic prospects. The government must act now to prioritize local needs, protect jobs, and ensure the continued growth of the mining sector.” Nyirongo concluded.
