SMAC to list on Toronto stock exchange

SMAC to list on Toronto stock exchange

Queensland-based SMAC (Strategic Minerals Acid Critical) Developments says that it plans to list on the Toronto Stock Exchange in December to raise $1.3 million to fund a final feasibility study. The company is attempting to develop sulphuric acid production in northern Queensland to supply local industries. The company plans to initially build a 180,000 t/a sulphur burning acid plant at a site at Cloncurry, followed by a second phase which would involve developing a pyrite roasting plant to generate 550-600,000 t/a of sulphuric acid.

Queensland faces a shortage of acid if the Glencore Mount Isa copper smelter closes down. Mount Isa produces around 1 million t/a of acid. Glencore says that the smelter is losing tens of millions of dollars per month, and in spite of an A$600 million bridging loan from the Queensland government, it is slated to close in 2028. The smelter is the main supplier of acid to Dyno Nobel’s Phosphate Hill facility, which uses up to 1.2 million t/a of acid. Aside from the Mount Isa supply, the balance comes from Sun Metals’ zinc smelter in Townsville. More acid could be required by the expanding vanadium industry in the state and copper leaching operations. Explosives company Dyno Nobel has said that it may cease operations at its fertiliser plant in September 2026 if a buyer is unable to be secured by March next year.

SRU commissioned at Petrobrazi refinery

Romanian oil and gas group OMV Petrom has commissioned a new sulphur recovery unit at its Petrobrazi refinery, near the southern city of Ploiesti. Development work on the new SRU began in 2023, and represents the second at the site, treating acid gas produced during the refining process. The euro 45 million investment is part of euro 2 billion of improvements that have been made over the past 20 years as part of the company’s strategy to modernise its refining capabilities, aiming to reduce environmental impact. Last year, the company said it would invest around euro 750 million to build several sustainable fuel plants at the refinery, which are expected to become operational in 2028.
