14/11/2022FDF metallurgical test results indicate that the deposit is variable in mineralogy and particle sizing. Preliminary test work suggests that metallurgical recoveries for Sn of 40 - 50% could potentially lead to the production of low-grade tin concentrates. This is in line with early estimates by the company.

25/08/2020There are three steps of the high-temperature system: Drying or preheating, calcining, and sintering. The calcining is the core part of the clinker production; the raw meal is weighed and sent into preheater and cement kiln to process clinker. Grate cooler helps to cooler clinker, the cooled clinker is sent to the cement silo for storage.
