and introduces critical flotation reagents such as sodium carbonate and sodium silicate, while the second tank dilutes pulp density to
around 35% solids. Following conditioning, pulp will be transferred to a scheelite rougher flotation bank consisting of four 30 m³
flotation cells. Reagents, specifically TOFA as a primary collector, will be added to promote efficient scheelite mineral attachment.
Rougher concentrate will proceed to the cleaner flotation circuit, while rougher tailings will be directed to scavenger flotation cells
for further recovery.

Tailings from the
scheelite rougher flotation circuit will be pumped to the scavenger circuit, consisting of two separate banks of four 30 m³ flotation
cells each. Before entering the scavenger flotation cells, the pulp will undergo additional conditioning where reagents, primarily TOFA,
will be reintroduced to improve flotation effectiveness. The scavenger flotation stage is designed to capture scheelite particles that
were not recovered in the initial rougher stage, to enhance overall tungsten recovery. Scavenger tailings, after passing through an inline
sampler for continuous monitoring, will be considered final tailings and pumped to the tailings thickener for dewatering and disposal.
The scavenger circuit is very important in minimizing tungsten losses.

The scheelite cleaning
circuit provides a multi-stage flotation process for the final upgrading of scheelite concentrates derived from rougher and scavenger
flotation stages. This circuit comprises four sequential cleaning stages. Cleaner stage 1 consists of three 5 m³ flotation cells,
while cleaner stage 2 utilizes two OK1.5 flotation cells. The final two cleaning stages (cleaner stages 3 and 4) will each utilize two
OK0.5 flotation cells arranged sequentially. Throughout the cleaner stages, sodium silicate will be continually dosed as a depressant
to prevent unwanted mineral flotation, to produce high purity scheelite concentrate. Temperature-controlled conditions (approximately
30–32.5°C) will be maintained using a heated water system to assist flotation performance. Concentration from the final cleaner
stage, after upgrading, is directed towards concentrate thickening and filtration processes, in order to achieve the required market
specifications of approximately 65% WO.

The final tailings
from the concentrator plant, along with effluent from the paste plant, will be collected into a feedbox, for a 20 m diameter High-Rate
Thickener (HRT).
