Making Ends Meet

Several trends are taking place in the mining business. Mining companies are investing in operations, but they have to justify those investments with a healthy rate of return. Cost overruns have simply become unacceptable. They are also looking for ways to improve profit margins by reducing costs at profitable operations and idling those that are either less profitable or losing money. In many cases, they are looking to mechanization, automation and information technology to assist in that endeavor. The major mining companies are also selling or spinning off noncore mining operations to generate cash or get them off their books. A noncore asset could be a mine that produces an outlying metal or mineral with which they no longer have an interest; it could be located in a region they no longer find trustworthy; or both.

The News this month opens with a discussion of Barrick Gold’s future growth plans in Nevada. Recently, Barrick said its five cornerstone mines in the Americas are expected ......... read more

Design Flaw Cited in Mount Polley Dam Failure
The massive tailings dam failure at Imperial Metals’ Mount Polley copper-gold mine in south-central British Columbia, Canada, on August 4, 2014, was the result of failure of a glaciolacustrine layer (clays and silts left behind by a retreating glacier) about 8 m below the base of the dam in the area of the breach. The Mount Polley Independent Expert Engineering Investigation and Review Panel, appointed following the tailings dam..... read more

The EPCM Perspective
Mining and metallurgical companies rely on specialist contractors to handle their big development and expansion projects. E&MJ asked some of the world’s leading EPCM providers for their views on a range of important issues

By Simon Walker, European Editor

With greenfield developments and expansions to existing operations alike often carrying budgets that run into billions of dollars, mining companies need to ensure that they are spending their shareholders’ money in the most effective way. And, of course, mining companies may be good at mining, but that is no guarantee that they have the experience or personnel resources to be able toundertake major projects on an in-housebasis. Even the largest in the world cannot afford to maintain their own dedicated design and execution team on the off-chance that a suitable project will become available……. read more
FEATURE - Energy Efiiciency
Identify Energy Efficiency Improvements to Cut Operating Costs
A combination of economic pressures, technological advances and higher awareness of available options is driving the industry’s interest in saving kilowatts

It’s obvious, even to a casual observer hearing a mile-long coal unit train rumble by or watching haul trucks climb out of a copper pit on a cable channel’s "world’s biggest" documentary, that mining is an energy-intensive industry. But its relationship with energy goes beyond the obvious—apart from being an energy customer, it’s also a supplier to the energy sector, providing fuels such as coal and uranium as well as the iron, copper, and other metals needed for production and generation; and it’s often an energy producer itself, building power facilities in remote locations where there simply is no energy infrastructure of any sort in place ..... read more

Bauxite and Alumina: Growth Maintained
Aluminum demand is predicted to continue growing strongly into the foreseeable future—consequently, the world needs more bauxite. With the market now in deficit,E&MJ looks at trade trends and potential projects.

By Simon Walker, European Editor

In January 2014, the Indonesian government put a cat amongst the pigeons with the introduction of its ban on exports of unprocessed raw materials. And while public attention focused mainly on the country’s copper producers—with Freeport subsequently being able to resume concentrate exports while committing to the development of new domestic smelting capacity—the ban also had a substantial impact on other mineral products, including bauxite and nickel laterite ore…... read more
FEATURE - Condition Monitoring
Condition Monitoring of Critical Mining Conveyors
Conveyor systems, integral to operations, require conditioning monitoring to ensure uptime

By Todd Schools

Increasing reliability and lowering maintenance costs are key differentiators in today’s highly competitive mining environment. Understanding mine equipment criticality and failure shows where maintenance effort should be focused to mitigate risk. One of the areas of focus based on criticality is conveying systems. These conveyors are typically single points of failure and, therefore, have high criticalities. The conveying system’s multiple rotating components, length and remoteness increase the complexity of maintaining these systems. A dedicated condition monitoring system can dramatically increase the reliability of a site’s conveyors..... read more

Conveyor Skirting Self-adjusts to Compensate for Wear
Martin Engineering said its new selfadjusting skirting prevents spillage and equipment breakdown caused by fugitive material by creating a constant tight seal to the belt. The unit self-adjusts to rubber skirt wear, regardless of material volume and size diversity. As the friction from the belt wears down the seal strip of standard skirting systems, workers have to shut down the conveyor and use tools to manually adjust it. Without this type of regular maintenance, fugitive material escapes from the belt, getting into bearings and …. read more
Flexible Coupling Speeds Conduit Installation
The new T&B Fittings nonmetallic expansion/deflection coupling from Thomas & Betts is claimed to improve safety and reduce installation time for joining rigid polyvinylchloride (PVC) conduit that is subject to movement in any direction at structural joints. According to the vendor, its design makes the coupling up to five times faster to install, while its versatility enables a five-to-one reduction in stock keeping units (SKUs). The coupling provides a flexible connection of PVC conduit runs that resists moisture …… read more
