This was despite a slowdown in global auto production, for which Johnson Matthey produces autocatalysts.
Palladium production rose 26% on the back of the ramp-up of the Phase 1 expansion at Zimplats, additional deliveries of palladium-richer autocatalysts and the continued destocking of material from the refinery.
Matthey is braced for an 11% drop in global car production in the period, resulting in reduced demand for autocatalysts, but it said the stronger dollar and cost efficiencies should help offset some of the slowdown.
While the group, which is a leading producer of autocatalysts for the automotive industry, warned that it would be hit in the second half by falling global car sales, process technologies, based at Billingham and Stockton, had benefited from tightening environmental legislation.
