On July 18, the sulfuric acid market in Hunan was mainly stable. So far, the mainstream factory price of 98% of smelting acid in Hunan has ranged from 50 to 160 yuan/ton. The production of acid factories in the area is stable, and the downstream main supply is to the chemical industry. There has been no significant positive results in the near future. Supply and demand in the region have remained relatively balanced. Demand in the peripheral Hubei region has improved, and there has been no shipment to the region recently. There is room for improvement in demand in the subsequent manganese triangle area, and in addition to the maintenance plans of some units in the main acid plants in the area, the acid price in the area will be stable, medium and strong in the subsequent period.
