Rocklands copper mine debuts ... tonnes per annum processing plant with a crushing circuit, high pressure grinding rollers (HPGR), scrubber, gravity circuit, ball mill, floatation circuit, a ...
The copper processing plant was designed to treat 1.3 Mtpa ROM ore to produce 60 000 tpa of copper cathode. Commissioning of the processing plant was completed in mid March 2005 with ramp up completed in January 2006 with 5260 tonnes of cathode harvested in this month. The focus of this paper is on Sepon's unique grinding circuit.
A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

FL to help modernise crushing, grinding circuit at Zijin's Serbia copper op Posted by Daniel Gleeson on 7th August 2019 Zijin Mining Group has chosen an FL gyratory crusher, SAG mill and ball mill for the Majdanpek mine, part of the Chinese mining company's majority owned Zijin Bor copper mine.
1 Over the past 15 years, mine-to-mill studies have focused attention on the impact blast fragmentation has on concentrator throughput. Blasting provides the first opportunity for comminution – or size reduction. It is also a cheaper and more efficient process, compared to both crushing and grinding.
The ore is stockpiled before transferring into the grinding circuit. The grinding circuit includes a semi-autogenous ball milling-crushing circuit containing a SAG mill and two fixed speed ball mills. The processed ore is then sent to the 28Mt/y concentrator plant containing a copper and molybdenum flotation circuit. Ore processing

In a typical grinding circuit, ore is fed into the mills where abrasion, attrition and impact reduce its size, ABB says. Usually, the grinding circuit contains at least two interconnected mills with material classifiers (eg cyclones) separating the fine material from the coarse (that then goes for regrinding).
