Marimaca Copper Corp. says that it has recently executed a binding asset purchase option agreement to acquire a used sulphuric acid plant in Chile from CEMIN Holding Minero. Sulphuric acid is one of the key input costs for the Marimaca Oxide Deposit, and the ability to produce a significant amount of its own supply will reduce exposure to a volatile acid market. The agreement has an exclusivity period of three months to allow further detailed technical and engineering reviews including capital and operating cost estimates for the installation and operation of the 150,000 t/a sulphuric acid plant, whose output would represent approximately 30-40% of total acid consumption at the Marimaca Oxide Deposit, depending on the phase of development. Marimaca says that, based on market research and quotations received, the estimated equipment cost of a new sulphuric acid plant of similar capacity is approximately $35-40 million, with a total installation cost of $50-60 million. The cost of breaking down and relocating the plant to the site at Mejillones and the start-up costs of the used plant are expected to be materially lower than cost of new equipment. Indicative operating costs show the potential for an approximately 30% reduction in acid cost relative to current long-term forecast and normal historical spot and contract acid prices delivered to Mejillones.

• The global sulphur market is forecast to enter a downward trend as supply from Saudi Arabia normalises following the summer months, while demand decreases alongside demand for phosphate fertilizers. The price is expected to fall towards the end of the year, with a low of around $220/t by May 2026.

A formal signing ceremony has been held between senior company executives from KMG PetroChem, Tecnimont and the Kazakh government for the construction of the new Tengiz Gas Separation Complex (GSC) project. The ceremony was held at KMG PetroChem headquarters, in the Atyrau region of Kazakhstan. The Tengiz GSC project’s scope of work includes engineering, procurement, construction and commissioning works, with Tecnimont mainly responsible for the EPC works. Completion is expected by the first quarter of 2029. Once completed, the gas processed by the GSC will feed the Silleno petrochemical plant, another project currently being executed by Tecnimont in the region. The GSC is designed to recover at least 98% of ethane from dry gas, while the Silleno complex is expected to deliver high-quality petrochemical products. KMG PetroChem is a fully owned subsidiary of Kazakhstan’s national oil and gas company KazMunayGas.

The global sulphur market registered price increases during August as a result of demand in Asia and North Africa, while supply has tightened due to limited supply from the FSU and Saudi Arabia, as well as logistical constraints in both Iranian ports and railway capacity to Black Sea ports.

The El Teniente mine, located in the O'Higgins region, suffered a collapse on 31 July. The collapse in the Andesita sector of the mine is understood to have been as a result of seismic activity that registered 4.2 on the Richter scale. It remains unknown whether the seismic activity was caused by the mining operations or natural activity, according to industry sources. Underground operations are to be halted for an unknown period of time while the open air sector, which represents around 10% of the total production, will remain open, according to industry participants.

Sulphur output in North America continues to decline due to refinery closures and conversions at the same time that acid demand is increasing for metals processing projects.

Gunnison has started producing pure copper cathodes at its Johnson Camp Mine (JCM) in southeast Arizona, United States, from a solvent extraction-electrowinning (SX-EW) circuit and using leaching technology from Rio Tinto-owned Nuton. As well as giving Gunnison exclusive rights to deploy the proprietary process on run-of-mine ore, Nuton is a financial partner of the Phoenix-headquartered mine developer which has restarted copper production at past-producing JCM. The company’s next goal is to ramp-up to nameplate plant capacity of 25 million lbs/year (11,300 t/a) of finished copper.

Nitric acid demand continues to be dominated by fertilizer uses via various nitrate and NPK fertilizers, but industrial chemical production, metallurgical uses and explosives production are continuing to contribute to growth, especially in Asia.

Transition Industries LLC has signed a heads of agreement with Italian contractor Bonatti SpA to deliver key infrastructure for the Pacifico Mexinol green methanol project in Sinaloa. Under the agreement, which includes a fixed lump-sum price, Bonatti will handle detailed engineering, procurement, construction, pre-commissioning, commissioning and startup for upgrades to the Terminal Transoceánica de Topolobampo port facilities. The work will cover methanol loading operations for export, underground transfer pipelines, vapor recovery systems, and dual fiber optic cables linking the main plant to the port. Bonatti may also build a closed-loop water pipeline to recycle municipal wastewater for plant operations, avoiding freshwater use and reducing environmental impact.
