We look at state-of-the-art technology used in phosphate and potash mining, including equipment and systems for excavation, tailings thickening, transport, tunnelling and processing.

With more than 15 million hectares of land watered by drip irrigation globally, the technology’s agricultural potential remains enormous. Fertigation – the ability to manage and regulate both water and plant nutrients – is a key advantage helping drive worldwide growth.

China’s copper industry is facing difficulties caused by the coronavirus outbreak in the country. Prolonged factory closures, particularly in Hubei province, at the centre of the outbreak, as well as neighbouring Guangdong and Zhejiang, also badly affected, have caused a slump in demand for copper domestically as copper fabricators remain on extended closure. However, smelters have resisted cutting production. Daye Nonferrous, based in Huangshi at the centre of coronavirus outbreak, continues to operate at 80% of its 600,000 t/a capacity for 1Q 2020, according to the company, in spite of quarantine and transport restrictions which have reduced truck shipments to the smelter – Daye is reportedly still able to receive copper concentrate shipments via the Yangtze River to Huangshi port.

Lessons can be learned from the challenges faced during the construction, commissioning and start-up phases of major projects. In this article challenges and experiences are shared from the recent successful commissioning of ammonia and urea plants around the world, including projects in Indonesia, India, Egypt and the Middle East.

The Abu Dhabi National Oil Co. (ADNOC) has awarded two EPC contracts with a total value of more than $1.65 billion for the offshore Dalma sour gas development, 190 km northwest of Abu Dhabi city. Dalma is one of the fields in the offshore Ghasha ultra-sour gas concession, which ADNOC views as central to the UAE achieving self-sufficiency in domestic gas supplies.

New ammonia and urea plants in Nigeria and Ethiopia are part of a wave of new capacity in Sub-Saharan Africa, and may help pull up regional demand from its current low base level.

At the Nitrogen+Syngas Conference 2020, held in The Hague, Netherlands, Haldor Topsoe launched its new TITAN ™ series of steam reforming catalysts. The company says that the new series, which consists of the RC-67 TITAN and RK-500 TITAN catalysts, offers improved performance and longer catalyst lifetime thanks to the hibonite-rich composition. The addition of titanium promoters adds exceptional mechanical strength while a seven-hole cylindrical shape yields both a very low pressure drop and a high surface area. Pressure drop build-ups in syngas plants can cause unscheduled downtime and cost millions of dollars, while thermal instability during operation can lead to operational risk and reduce plant lifetime. Topsoe says that the catalysts can mitigate these risks, ensuring lower operating costs, increased profit margins, and reduced energy usage.

Andy Hemphill , senior editor for potash at ICIS Fertilizers, takes a deep dive into the potash market. Potash producers are praying that tight capacity control and resurgent demand will curb the current bearish price trend.

The Ma’aden Wa’ad Al Shamal Phosphate Company (MWSPC) has signed a service agreement for a period of three years with DuPont Clean Technologies for its sulphuric acid plant at Sirhan. The service programme will include activity testing of catalyst samples, evaluation of catalyst performance, plant optimisation, troubleshooting and management of catalyst replacement. DuPont says that it will also track plant performance and assess its overall health using pre-agreed metrics and its proprietary PeGASyS™ gas chromatography system, which can be used to detect possible leaks in gas-gas heat exchangers, identify SO2 gas bypassing and measure overall plant conversion in order to optimise plant operation, reduce SO 2 emissions, increase production and improve converter performance.

Sirius Minerals is in talks with Anglo American about a £386 million cash offer for its UK-based polyhalite mine project.
