  • Tianzhu Chemical is aiming to produce 500,000 tpa barite from the Tianyan mine, split between chemical and drilling grades. The mine's current capacity is 300,000 tpa, with sales of 170,000 tonnes in 2015. The company operates bagging facilities and two Raymond Mills for processing Tianyan barite, with a combined capacity of 100,000 tpa <200 mesh barite powder.

    Rocky Mountains also has 51% share in the Yanhe white barite and fluorite (CaF2) deposit in Guizhou. The mine has a capacity of 30,000 tpa barite but current production is just 10,000 tpa. The barite-fluorite vein is four metres wide and jigging trials have been successful in separating most of the barite in the ore. The SG of the barite varies from 4.25 to 4.35 and it can be transported by either river barge to port or truck to beneficiation facilities in Guangdong.

    The Sanjiang barite deposit in Guangxi is 100% controlled by Rocky Mountains. It contains stratiform barite, dipping at around 70-80 degrees. The mine is not yet producing but detailed jigging trials have being carried out to improve the SG of the barite recovered. These trials have used a feed of 3.60-3.70 SG barite, which has been crushed to a size of 0-6mm and jigged to produce material with SG of 4.05-4.10.
