Tenova DELKOR says it has successfully supplied and carried out mechanical completion of seven DELKOR thickeners, together with its flocculation system and a DELKOR Pinned Bed Clarifier (PBC) for a silver leaching plant project in Morocco.

The thickeners are to be employed in the counter current decantation circuit of the plant, with the project including the design, fabrication and supply of thickeners, flocculation plant and PBC, supervision of installation and performance guarantee.

The PBC is a unique process for hydrometallurgical plants where solution clarity is important, according to the company. “A technology for polishing feed solutions for solvent-extraction plants, the unit offers low suspended solids counts in overflows, regularly achieving clarities of less than 50 ppm solids, and as low as 20 ppm.”

Benefits of the PBC technology, according to Tenova DELKOR, include low capital expenditure for comparative clarifying technology; no moving parts, virtually eliminating the need for maintenance; robust and stable performance; it is optimised to minimise flocculant consumption, and; a small footprint.

Ramesh Mahadevan, DELKOR India Managing Director, said: “As the industry specialist in sedimentation, DELKOR offers a range of thickeners and clarifiers catering to various applications across the minerals, chemical, industrial and water management industries with designs of up to 100 m in diameter.

“Successful hand over of this important project only serves to strengthen our capabilities in the North African region and is a true testament that.”
