Belaruskali and Belarusian Potash Co. (BPC) have reported their availability of white potash for the market will be limited for the next three-to-four weeks due to repair work and scheduled maintenance at production unit 4. The repair work follows the collapse of the metal structure of the conveyor gallery at the site on Oct. 26 just ahead of the scheduled annual shutdown of the production unit for maintenance. The production unit 4 produces about 280,000 mt per month of white potash. Belaruskali and BPC said in a statement most shipments of white product will be carried out as planned and outstanding volumes will be delivered immediately after the production unit 4 resumes operations. The companies said the reasons for the incident are being ascertained, and that there were no injuries.
