Minerals Processing, Process Control
Consultant's Comment: Water, our most precious mineral
Water plays multiple roles at mine sites. Often water is a part of the mining process, as with hydromining; dredging and in situ leaching. Water is an integral part of mechanical mining being used for dust suppression.
Aluminium could hold key to Ranger water purification
CSIRO staff have been working with mining company ERA in developing a process to purify water used in the processing of uranium so that it can be disposed of safely.
FLSmidth releases ‘next generation’ disc filter
FLSmidth engineers have adapted their site-proven eductor feed agitation technology to a new disc filter and, in the process, eliminated many of the problems that have plagued disc filter efficiency in minerals processing.
Outotec Vane Feedwell™ in more than 50 installations worldwide
At the end of 2008, Outotec launched a high-performance feedwell designed to significantly increase efficiencies in thickening and clarifying applications.
Virtual flotation cells stir up industry interest
When it comes to separating valuable minerals from gangue, the minerals industry is perpetually striving for greater operational efficiency.
A guide to achieving process stability using your existing plant control system
Achieving stable pulp levels throughout a flotation circuit can be a challenging task, but an essential one for maximising metal recovery and stabilising concentrate grade.
Investment in iron ore washing gathers pace in India
Two of the largest steel producers in India have recently purchased new iron ore washing plants from CDE Global through their sister company CDE Asia with headquarters in Kolkata, India.
Planning for mill installations
The milling/grinding area is traditionally known as “the heart of the plant”. So, when it comes to preparing its installation a great deal of planning is required.
First Vertimill® 3000-WB headed for Australia
The first 3000 HP (2240 kW) Vertimill, known as the VTM-3000-WB, is destined for Newcrest Mining’s Cadia Valley Operations, where it will be operated in a tertiary grinding role.
BIM – the new modelling tool for mines
Building information management or BIM is a new engineering modelling practise that allows mines to bring together all facets of engineering into a three dimensional, dynamic model of a proposed mine prior to construction and maintain a live record during operation.
The new generation of conveyor skirting
In many bulk materials handling plants, reducing the dust from conveyor transfer points subsequently reduces the risk of an employee’s exposure to Silica dust. The litigation costs associated with this condition rival that of asbestosis, costing billions of dollars.
Did the GFC signal the end of innovation in Australia?
Like many equipment manufacturers in Australia, ESS has witnessed competition from low priced copiers for a number of years. It believes that innovation is alive and well in the conveying services and technologies sector for a number of reasons.
Gas dispersion plays important role in flotation – Part two
It is recognised that successful flotation depends on the pulp and froth phases, but the gas phase also plays an equally important role.
Gas dispersion plays important role in flotation – Part one
It is recognised that successful flotation depends on the pulp and froth phases, but the gas phase also plays an equally important role.
Advanced precision bolting technologies from Outotec
Outotec is combining high efficiency hydraulic technology with advanced ultrasonic bolt load testing to optimise the speed, accuracy and safety of bolting operations in the construction of SAG and ball mills.
Thickener tank design options for operational and cost efficiency
When the GFC hit in early 2009, the mining industry was dealt some tough challenges, with everyone forced to tighten their belts and cut costs wherever possible. Now, projects must ensure that the most efficient, cost effective solution has been chosen.
Magnetic separation for the mining industry
You wouldn’t think that magnets play an important role in the recycling, mining & quarrying industry, but they do. A magnetic separator is industrial equipment which creates a powerful magnetic flux.
Dewatering technology pays for itself in two years
Minimising stress on scarce water resources is becoming a major issue for resource developments in Australia - and for every country that has limited access to resources.
FLSmidth thickeners for Lihir Island expansion
FLSmidth Minerals has been awarded a contract to supply two elevated thickeners for the expansion program at Lihir Gold Limited’s (LGL) giant Lihir Island gold mine in PNG.
Thickener sizing & the role of testwork – Part two
When planning a project that includes thickening technology, a key element is determining the sizing and expected performance for the thickener(s). This will facilitate project layout and design, as well as define capital expenditure and cost estimates.
