THICKENING & FILTRATION
proprietary low-profile style with tubular rake arms . These are able to move high-yield stress material with minimal drag and torque exerted on the drive mechanism .
Areington emphasises that all mechanical elements are designed for long life . This limits the intervention of the plant personnel to regular maintenance . Most of the large thickeners operating in the southern African market - up to 120 m in diameter - have been supplied by FLSmidth . He highlights FLSmidth ' s impeccable group pedigree in terms of thickeners . “ Our large installed base of units around the world is testament to our cuttingedge thickener technology ,” he says . “ We have also secured most of the market for paste thickeners globally .”
FLSmidth ' s involvement with the Mozambique project goes back almost a decade to the first phase of the plant ' s development , according to Vice President Mining in Sub-Saharan Africa , Middle East and South Asia , Alistair McKay .
FLSmidth was recently chosen as the preferred provider for four large bolted thickeners for a large customer in Mozambique
Despite the COVID-19 lockdown , good progress was made on the fabrication of the thickeners in South Africa , according to FLSmidth Project Manager Kevin Kockott . This has been managed by leveraging FLSmidth ' s global resources and the design teams ' ability to work remotely . The design of the thickeners features FLSmidth ' s well proven bridge-mounted rake drive , known for its simplicity and ease of operation . The rake mechanism includes a
ANDRITZ delivers at Comika in DRC
Looking at innovative thickener installations , ANDRITZ recently completed a major project at the Comika copper-cobalt operation in DRC . Much of today ’ s consumer technology relies on cobalt , and 60 % of the world ’ s reserves of this sought-after element are located in the DRC . The former Katanga province in the DRC ’ s southwest is particularly rich in cobalt and copper , and this is where Norinco International , an incorporated company affiliated to China North Industries Corporation , operates an ore production facility called Comika .
In 2018 , Comika was already beneficiating sulphide ore and moving into oxide ore . Unlike sulphide ore , the beneficiation of oxide ore involves acid leaching , where the copper is liberated by the addition of sulphuric acid . The liquor , commonly known as PLS ( pregnant leach solution ), is an acidic , metal-laden liquid that needs to be clarified – or beneficiated – to separate the leached copper . A thickener , or
