The ore processing facility consists of conventional crushing, grinding, selective flotation, and pressure filtration. The facility is equipped with an online Yokogawa process control system and also an SGS Expert System. Crushing is done in three stages. A primary jaw crusher located close to the ore storage bins does the first stage crushing.

Large pieces of ore are broken once, and then fall to a lower position (because they are now smaller) where they are broken again. This process continues until the pieces are small enough to fall through the narrow opening at the bottom of the crusher. A cone crusher is suitable for crushing a variety of mid-hard and above mid-hard ores and rocks.

Crushing processes taking place in high-pressure grinding rolls devices (HPGR) are currently one of the most efficient methods of hard ore size reduction in terms of the energy consumption. The HPGR products are characterized by a fine particle size and the micro-cracks formation in individual particles, which appears in downstream grinding processes, decreasing their energy consumption.
