Operating rates of China silicon plants rallied to 33.3% in April as mills in south-west reopened

Published: May 13, 2020 11:09
Resumption of production in Yunnan and Sichuan accounted for the rally in April’s operating rates. Silicon plants in Nujiang of Yunnan and Ngawa and Leshan of Sichuan reopened part of their capacity ahead of the arrival of rainy session, and this offset some capacity curtailment in Xinjiang and Chongqing due to losses and tight ore supply.

SHANGHAI, May 13 (SMM) – Operating rates across Chinese silicon metal producers rebounded in April from a four-year low level a month ago, rising 3.3 percentage points on the month and 0.1 percentage point on the year to 33.3%, showed an SMM survey. 


The average operating rates for May is expected to further recover to 36%, SMM estimates. 

  


Resumption of production in Yunnan and Sichuan accounted for the rally in April’s operating rates. Silicon plants in Nujiang of Yunnan and Ngawa and Leshan of Sichuan reopened part of their capacity ahead of the arrival of rainy session, and this offset some capacity curtailment in Xinjiang and Chongqing due to losses and tight ore supply. 


The average operating rates of silicon producers in Yunnan increased 11 percentage points on the month to 25.9%, with the rate in Sichuan climbing 8 percentage points to 18.5%.


The respective rates in Yunnan and Sichuan are likely to rise to 36% and 21% in May as Nujiang of Yunnan enters the rainy season and the dry season ends in Sichuan this month. Due to current issues of low profits and lack of hydropower, greater-scale resumption of operations is expected in June when a full-scale rainy season arrives. 


As the ore shortage problem lingers in Xinjiang, a local large-sized producer lowered operating rates to 70% in April to prolong the use of silica. Another major plant in Xinjiang kept running at less than 30% of its capacity as it failed to secure alternative sources of silica. Other small mills in Xinjiang also scaled back production amid limited profits. 


SMM assessed the average operating rate of silicon plants in Xinjiang at 33.1% in April, down 2.8 percentage points from March.

In H1 2026, Americas moly supply divergence deepened. Despite stronger mining profits, overall output failed to rebound. While H2 may see recoveries at select large mines, supply elasticity remains constrained. Which operations are dragging on supply, and where will incremental growth emerge? SMM data reveals a market entering a new phase of "stronger margins, diverging production, and concentrated incremental gains."...

[SMM Chromium Flash] Tharisa's Underground Transition at Its Chrome-PGM Flagship Mine Remains on Track
Tharisa confirmed its transition to underground mining at its flagship Tharisa Mine, on the southwestern limb of South Africa's Bushveld Complex, remains on time and within budget, running in parallel with the Karo Platinum Project's construction financing in Zimbabwe. Development of the Apollo underground complex, which commenced in March 2026, is progressing toward first run-of-mine ore in the current quarter, with steady-state production of 255,000 mt per month targeted by the third quarter of calendar year 2029. The Orion complex is expected to follow, targeting first ore in financial year 2031 and steady-state production by the third quarter of calendar year 2033. Together, Tharisa said the two underground complexes are expected to extend mining at the Tharisa Mine, which co-produces chrome concentrate alongside PGMs from the same orebody, for more than 60 years beyond depletion of the current open pit. The underground project is fully funded through development loans from Absa and Standard Bank and an asset-based revolving facility from Nedbank, funding that sits separately from the US$300 million Nordic bond raised this week for Karo. The company did not break out what share of Apollo or Orion's future run-of-mine ore output will be chrome-bearing material versus PGM-bearing material, leaving the underground transition's specific impact on Tharisa's chrome concentrate volumes still to be clarified as the two complexes ramp up toward steady state.
