Condition monitoring in mining maintenance: Scalable, customisable solutions

The first signs of impending breakdown in machinery typically include tiny changes in vibration that warn of excessive wear in the bearings upon which efficient functioning depends. Left unheeded – because they are notoriously hard to detect – these subtle rumbles lead to energy wastage, under-performance and costly inefficiency as slow-motion failure sets in. Ultimately, if still undetected, the deterioration progresses to full-scale breakdown, with downtime, lost production and often hazardous removal and replacement of the offending parts deep in the heart of vital process machinery. The best cure is…

Coronado Coal global operations hit by US-China trade wars

Coronado Coal expects the impact of the US-China trade wars will push its revenue lower and its earnings below the bottom end of its guidance range. With the trade negotiations remaining unresolved, China has not yet granted relief on tariffs. Coronado had to cease its shipments to China from its Buchanan operation in Virginia, the United States in September. This further increased company inventories rather than selling at depressed prices. Europe and Brazil were also showing subdued demand for metallurgical coal, according to Coronado managing director Gerry Spindler. The benchmark…

ERA shareholder demands scrapping of Rio-backed raising

The Takeovers Panel has received an application from Zentree Investments following Energy Resources of Australia’s (ERA’s) launch of a share entitlement offer last week. ERA announced plans to raise $476 million to cover the rehabilitation of the Ranger uranium mine in Northern Territory last Friday. Zentree has submitted the application because it believes minority shareholders are not being given equal or reasonable opportunity to participate in the benefits flowing to Rio Tinto. It also stated, “there has been inadequate disclosure as to the need, size and urgency of the entitlement…

Diversity debate aligns on need for multi-dimensional approach

The Gold Industry Group’s (GIG) annual Women in Gold Great Debate this year tackled the topic ‘a diversity debate that begins and ends with gender is doomed to fail.’ Australian Mining watched in Melbourne as four speakers faced off with vastly different examples of how this topic was a part of their careers and personal lives. Gold Road Resources general manager for capability and culture Stuart Jenner teamed up with Kirkland Lake Gold environment and community manager Felicia Binks to take the proposition, while Newcrest Mining principal for diversity and…

Reclaiming the bearing health of bucket wheels

Bucket wheel reclaimers play an integral role in the iron ore sector. They are also vulnerable to contamination from dust and other particulates that cause problems to their functionality. As CBC engineer Harrison Hart explains, if a bucket wheel reclaimer fails and causes downtime, this can cost hundreds of thousands of dollars in lost production. Which is why his role at CBC focuses on providing the iron ore sector with robust products and extensive servicing to prevent failure of critical machinery such as the bucket wheel reclaimer. Based in Western…

Clive Palmer diversifies Mineralogy portfolio in WA

Clive Palmer has expanded Mineralogy’s operations in Western Australia by acquiring a long-term lease of an 1100-square-metre commercial property in Perth. Mineralogy will use the leased office to accommodate visiting executives. The profits of the multi-billion Sino iron joint venture (JV) project with Chinese state-owned CITIC grew by 88 per cent in the last 12 months in Australia and China, which Palmer attributed to “our quality iron ore.” “Nobody expected back in 1985 that this project would be so successful and create so much wealth for this country,” Palmer said.…

Galaxy targets ‘value over volume’ at Mt Cattlin

Galaxy Resources is cutting back activities at the Mt Cattlin lithium mine in Western Australia, riding out poor market conditions until the demand for battery minerals improves. This decision comes despite the Ravensthorpe spodumene and tantalum operation delivering a record year for production volume, operating cost and product quality in 2019. In the third quarter of 2019, Mt Cattlin produced 50,104 tonnes of lithium concentrate, which was the midpoint of its 45,000 to 55,000 tonne guidance. Galaxy stated its corporate strategy for Mt Cattlin in 2020 was “to prioritise value…

Saracen swoops on Barrick stake in Super Pit for $1.1bn

Saracen Mineral Holdings has emerged as the successful bidder for Barrick Gold’s 50 per cent interest in the Super Pit gold mine in Kalgoorlie, Western Australia.

Barrick chief executive Mark Bristow said the sale of the company’s non-operating interest in the Kalgoorlie Consolidated Gold Mines (KCGM) joint venture represented the first step in its plan to dispose of non-core assets…
