Chinese phosphate exports
Although China remains the world’s largest phosphate producer, it has been overtaken as the largest exporter by Morocco in recent years as domestic producers face continuing restrictions on exports.

Chile’s environmental regulator SMA has filed a charge against state-owned Codelco, alleging emission violations at its Potrerillos copper smelter in the Atacama region of northern Chile. An audit showed the company had not implemented a monitoring system for sulphur dioxide emissions and other procedures in accordance with environmental standards for the plant, Reuters news agency reported. The SMA labelled the charge as serious, which could lead to a fine of around $4.1 million, and possible revocation of the environmental permit or closure. Codelco had ten days to submit a compliance plan, and 15 days to present a defence.

The Caspian Sea region is home to extensive sour gas reserves which produce large volumes of sulphur. Exports are difficult, but the Kazakh uranium industry is consuming an increasing amount.
Sulphur prices may remain stable before decreasing on muted demand and transactions may increase in frequency contributing to price decreases in the first half of 2025.
Short term supply constraints are dominating acid markets at present, but increasing smelter production across Asia may lead to oversupply in the longer term.
Demand for nitrates has rebounded after a difficult period following the dislocations caused by the war in Ukraine, with UAN in particular seeing rapid growth. Technical ammonium nitrate is also growing on the back of increased mining activity.
Part 1 of this series on stripper efficiency issues provided a brief history of the CO₂ stripping process and discussed how the invention of the HP CO₂ scrubber back in the 1960s revolutionised urea technology. In part 2 we take a look at how high liquid load can affect stripper efficiency.
Indian producers have begun producing nanofertilizers at scale with the backing of the national government, as part of efforts to improve nutrient use efficiency, limit fertilizer subsidies and reduce fertilizer import dependency. But some scientists have questioned the claimed benefits and the overall efficacy of these novel crop nutrient products.
Levity Crop Science has a growing reputation as a leader in functional fertilizers, offering novel products that boost nitrogen and calcium efficiency and the crop uptake of micronutrients such as boron, molybdenum and silicon. This has culminated in the recent completion of a new research and development centre near Preston in the UK.
