Aim-listed W Resources on Tuesday announced the first ore feed to the newly commissioned jig and mill plant at the La Parrilla tungsten mine in Spain.
This follows construction completion in April and commissioning of the conveyors, pumps, thickener, two mills and two jigs over the past month.
The jig and mill plant takes ore crushed to less than 10 mm and efficiently increases the grade to be fed to the concentrator plant, while efficiently rejecting waste mass. The jigged mine feed will be fed through the existing concentrator plant, while the new large-scale concentrator plant advances to construction completion in June and commissioning in July.
"At this stage of construction, it is important to clarify that commissioning a metallurgical plant is not a turn of a key process. In the jig and mill plant alone there are two jigs, two roll mills, a thickener, reject disposal system, ten screens and feeders, nine conveyors, five pumps, and over 50 motors which need to be started, aligned and tied into an integrated control system. The team has done an outstanding job commissioning the plant and achieving first jigged concentrate,” said W chairperson Michael Masterman.
He added that the great progress of the team kept the company on track to ramp-up to design production capacity of 200 t/m by the end of 2019.
