 Australia Imposes Unfair Taxes on MinersAustralia’s federal government recently announced a carbon tax scheme to reduce the country’s greenhouse gas emissions. The announcement came at a time when the Australian mining industry is still trying to calculate the impact of the draft legislation for the Mineral Resource Rent Tax (MRRT). Even though similar choices cost her predecessors their political careers, Australian Prime Minister Julia Gillard has stayed the course on MRRT and decided to impose a carbon tax.
While the major miners, who had a hand in rewriting the MRRT, are supporting it, smaller miners and explorers are crying foul. They believe the policy affects the development of future projects disproportionately to existing operations and a study from the University of Western Australia supports that belief. The UWA model shows that, under the MRRT, the average total effective tax rate increases from 38% to more ..... read more.

 World Gold Council Launches Initiative to Combat Conflict GoldThe World Gold Council (WGC), working with its member companies and leading gold refiners, has produced a draft framework for two standards designed to combat gold that enables fuels or finances armed conflict. Released for review and comment in mid-June 2011, the ‘Conflict Free Gold’ and ‘Chain of Custody’ standards seek to ensure:
• Where gold is mined in a conflict or high-risk zone, its production and/or transportation do not finance or benefit armed groups. .....read more

 Paste: A Maturing TechnologyMining companies worldwide are gaining the benefits from optimizing their tailings-disposal systems
By Simon Walker, European Editor
Paste technology covers a range of applications, all of which are founded on one basic concept: reducing the moisture content of a processing plant’s tailings stream to produce a material that remains sufficiently fluid to pump yet sufficiently stiff to gain early stability. Drivers for the use of paste technology include the need to conserve water resources, reducing the environmental impact of tailings disposal, hastening tailings restoration, and producing a material that has better properties for use as backfill underground. Key to the more widespread use of paste technology, whatever the reason for its application, has ....read more. |

With images of the earthmover tire shortages of 2007 still etched on the industry’s rear-view mirror, mine fleet operators and potential customers are again facing the prospect of ultra-large tire scarcity down the road—and once again, at a time when the industry’s strong resurgence after a major slump could be slowed by rising costs and material shortages. Overall operating costs are growing. Just recently, Wall Street research firm Sanford Bernstein reported that an average of announced first-quarter 2011 mining unit cost increases indicates they have risen by 18% year-on-year...... read more. |

In the never-ending battle to gain tighter control over flotation circuit performance, plant operators already have a wide spectrum of tactics and tools to choose from, ranging from eyeball inspection of froth characteristics based on prior experience, up to complete optical- or statistics-based control systems. Recent technological developments from two companies—one well-known to the industry, the other not quite as familiar—add even more options to the operator’s arsenal. Floating the Fines According to Wolfgang Krieglstein, sales and product manager, Siemens AG Mining, a mounting challenge to minerals processing is the issue of steadily declining head grades for valuable minerals in ore. ....read more. |

 Australian Expertise Comes with the Raw MaterialsBy John Miller, Australian Editor
Australia is not only supplying many of the raw materials feeding the ongoing economic development of emerging nations such as China and India, and supporting the industrial powers of Japan and South Korea, it is arguably the world’s premier supplier of mining technologies and services. The importance of Australia’s mining technology, services and equipment sector domestically and internationally was outlined at Austmine 2011 in Brisbane, Queensland. An under-recognized segment of Australia’s world-class minerals industry, the sector has expanded rapidly in the past decade, such that it is now estimated to generate A$30 billion a year of sales with annual exports worth more than A$8 billion.
