8 OPERATION FOCUS: Chelopech
The Chelopech mine in Bulgaria, a 100% owned subsidiary of Canada based Dundee Precious Metals (DPM) is well on the way to doubling ore production and processing to 2Mt/y. Part 1 focused on the steps being taken in the mine, and here John Chadwick examines the concentrator expansion and ongoing exploration
16 GREAT MINES – Lucky Friday
Celebrating 120 years this year, Hecla Mining is progressing deeper at Lucky Friday, the deepest operating mine in the US, which has been commercially producing silver since 1942
24 FLOTATION
John Chadwick examines new technologies and applications from some of the key players in mineral flotation, a technique that is so important to the global mining industry
42 BREAKING NEWS
John Chadwick considers eco-efficient comminution, new jaw and cone crushers, mills, mill linings and more
56 IPCC 2011 REVIEW
Paul Moore gives an in-depth account of the first IPCC event, run by IM Events and held in Belo
Horizonte from 21-23 September. The conference was a huge success both in terms of the quality and number of delegates to the breadth of material and insight in the program
64 MAINTENANCE AND RELIABILITY
A new regular column from Idcon’s Tor Idhammar is intended as a forum in Inteational Mining to discuss maintenance work processes and the management of maintenance
66 JUST IN TIME
A maintenance case study from the FMG iron ore operation in Australia, looking at how the mine
looks after servicing its sizeable fleet of Wirtgen surface miners
68 LOOKING EAST
Following IM’s attendance at the two leading mining events in Poland and Russia, namely the
Katowice and Ugol Rossii shows, Paul Moore looks at developments at a range of their
home-grown mining equipment suppliers
78 WEARING IT WELL
Mining often involves corrosive, very hard and abrasive materials, putting great stress on cutting heads, blades, crusher/mill linings, buckets and other components. Paul Moore looks at some of the market developments in wear parts and some of the speciality materials used
87 LINER LESSONS LEARNED
In SX-EW, for cost reasons there has been a move away from stainless steel mixer/settlers to lower cost concrete basins lined with high density polyethylene sheet/geomembranes
88 REMOTE SOLAR POWER
A look at power options for remote operations and the advantages of solar cells in certain situations
90 MINING TECHNOLOGY UPDATES
