:: allmineral Provides the Key Technology for Efficient Copper Ore Processing in Queensland, Australia


The mine operator CUDECO is banking on innovative allmineral technology for processing their native copper. As of mid 2013, the Chinese state company SINOSTEEL will bring into operation ten jigging machines type alljig® for treatment of various particle sizes as an integral part of their ambitious »Rocklands Group Copper Project«. allmineral’s technology, already operated worldwide by leading mining companies, will be the core equipment within this high-tech plant, which will produce high grade copper as well as marketable cobalt, gold, pyrite and magnetite concentrates over the next decades.

Formerly being a specialist in exploration only, internal restructuring made CUDECO become a copper mine operator. As such they are currently building a huge mine plant, just 17 kilometers west of Cloncurry (Queensland). In an area of a size of 16 hectares exploration results indicate prospects of up to 30 million tons of various minerals with high metal content. It is planned to mine and process existing resources in one of the technically most advanced processing plants in the world.

During the first years, the focus will mainly be on mining native copper next to the surface with an expected maximum copper content of up to 20%. In addition, copper sulfide and -oxide with traces of gold and silver will be mined, along with pyrite with traces of cobalt, gold, and silver as well as magnetite. All of these minerals will be processed and upgraded to high quality products for the global market.

On behalf of CUDECO, SINOSTEEL will build a unique processing plant utilizing the most advanced technologies available. A total of ten alljigs® designed and manufactured in Europe will play a key role in the process: Four coarse jigs (8 to 40 mm feed size, capacity of 110 tph each) as well as three medium jigs (4 to 8 mm feed size, capacity of 55 tph each) and three fines jigs (1 to 4 mm feed size, capacity of 45 tph each).

alljig®-jigging machines are the most popular allmineral technology throughout the world with close to 500 units supplied to date. Their state of the art air-/side-pulsed design allows for optimized jigging stroke generation along with high energy efficiency. The alljigs® in Queensland have an operational capacity of up to 740 tph and produce a remarkable high grade concentrate.
