Sargon Engineering

Boric Acid

borpic
 
Sargon Engineering has completed a number of project cases for the processing of Satimola borate ores to produce boric acid. We have a sound grasp of the various process options available, along with an appreciation of the associated costs.

Sargon Engineering is well positioned to provide process advice and consultation to clients seeking to develop Borate deposits. Our ‘can-do’ mentality and experience in Boric Acid production have led to Sargon Engineering carrying out a series of concept studies for the extraction of boric acid from the Satimola borate deposit for WorleyParsons, Kazakhstan, with the end client being Satbor. Sargon Engineering modeled the entirety of the process in METSIM, and formulated a conceptual cost estimate, based on a comprehensive equipment list and the project’s infrastructure requirements.

The final report, for a plant capable of 100,000 tpa, provided commentary on the following key areas:
