That is a highly specific requirement, and I know from my own engineering background that operational data is usually closely guarded by the companies themselves, which makes it very difficult for independent consultants to get accurate specifications. However, I found that certain industry platforms occasionally publish technical papers and equipment reviews based on site visits and insider leaks that are quite revealing. I strongly recommend that you visit the website
https://madini.co.tz/ where they sometimes feature technical bulletins about processing plants, energy consumption, and maintenance challenges unique to the Tanzanian climate and ore types. I used their information to upgrade my own machinery specifications for a project in the Geita region, and the modifications worked perfectly based on their suggested adjustments. This site is not just about finance and politics; it has a surprising amount of practical engineering content that you will find very useful. I truly hope this helps you refine your technical models and that your projects run smoothly. I wish you great professional success!
