mineral technologies launches new modular plant range

mineral technologies launches new modular plant range

Mineral Technologies (MT) has been leading the industry in developing new and innovative mineral processing solutions for over 80-years. Synonymous with gravity separation and world-class spiral technology, their latest range of Modular Plant packages deliver a combination of off-the-shelf modular design and engineering mastery.

Customisable to your specific ore body, the new range of Modular Plants offer the usual superior metallurgical performance that Mineral Technologies is known for. Not only is the price point attractive, they are also customisable, manufactured to the highest quality & safety standards, easy to ship to site, quick to assemble and commission, and completely relocatable. It's clear they've done the work - this product range is not just another modular plant in the market.

Launching the new plants, General Manager Alex de Andrade talked about the depth of knowledge and expertise that underpins Mineral Technologies' constant striving to find a better way' and improve mineral processing operations.

It's clear Alex is proud of MT's long and successful history, which he says has led them to "become a global leader in fine mineral separation. Initially running mining operations in Australia before moving to a technology-focussed business. Mineral processing is uniquely embedded in our DNA and explains why we've been involved in most of the world's major mineral sands projects and a growing number of iron ore projects".

Alex said that the innovation-led culture continues to deliver improvements in both equipment and plant designs for customers worldwide. The most recent solutions brought to the market include the Mobile Mining Unit (MMU), Lyons Feed Control Unit (LFCU) and now, their new Relocatable Modular Plants.

At the launch, Global Manager - Business Development, Matthew Allen said the new family of Modular Plants had been a year in the making, cleverly designed to deliver exceptional operational performance, whilst providing a speedy return on investment. With the option to easily transport the plants across sites, or to add modules at a later time, the new Modular Plants enable project teams to ramp up capacity and production outputs when and where necessary, to deliver real financial benefit.

"When we started to develop our new modular plant designs, we didn't want to compromise metallurgical process outcomes, which was a common feature of most modular plant designs. We knew there had to be a better way than the traditional one size fits all approach that forces customers into compromising both metallurgical and financial outcomes", said Matthew.

Well known for its spiral separators, of which the company is the world's leading supplier, Mineral Technologies is also recognised as the go-to supplier for process plant design including the world's largest mineral sands plant, Grande Cote in Africa.

With capacity from 5 t/h up to 300 t/h, the new range of Modular Plants enable Mineral Technologies process engineers to customise plant designs to suit specific ore bodies. Matthew spoke to the current issues that many customers are facing with more challenging ore bodies requiring more complex process solutions. He said this is evident in the increasing demand for MT smarts in new and upcoming projects.

"We wanted to help customers get operational faster despite the growing complexity of their ore bodies. With our in-house metallurgical testing, we can deliver the entire process. From initial mineral testing and flowsheet development, our experts can use the clever flexibility we've designed into our Modular Plant range to customise a solution specific to the orebody.", said Matthew.

The customisable modules have been designed to accommodate the full range of Mineral Technologies world-class spiral separators, which means there is no reason for a Relocatable Modular Plant not to have the world's best spiral technology.

Mineral Technologies' new range of Relocatable Modular Plants have also been designed to incorporate some of their latest innovations, such as the LFCU and CT1 spiral technologies, which have recently been trialled to show significant reductions in water requirements over traditional spiral plants. As described by Matthew "our recent trials, that combine the LFCU feed system with the latest CT1 compact spirals, have shown successful mineral separation at feed densities in excess of 60% solids (w/w). This means that this new technology has the potential to reduce water demand by almost two-thirds".

According to Mineral Technologies, this reduction in water being consumed by the plant means a significant reduction in the amount of water being sent to the tailings dams. This also leads to a substantial reduction in power consumption for tailings systems.

Mineral Technologies deliver innovative, cost effective process solutions for Iron Ore, Mineral Sands, Silica Sands, Coal, Chromite, Gold, Tin, Tungsten, Tantalum and a wide range of other fine minerals worldwide.

scale up and simulation of vertimill pilot test operated with copper ore - sciencedirect

Vertimill has been used in regrind circuits during the past years due to its greater efficiency when compared to the conventional tube ball mill. This paper presents the Vertimill pilot grinding tests with a sample of copper ore carried out in closed circuit with a high frequency screen. The sample was crushed 100% to <6mm. All operating variables were measured under controlled conditions to produce a mass balance of the test. A laboratory batch ball mill was used to characterize the sample in order to determine the energy specific selection function and the breakage function. Previous studies have shown that the Vertimill produces larger values of the selection function and a constant scaling factor can be used to simulate the product particle size distribution of the Vertimill from the batch ball mill grinding tests. The results of the simulations showed that it is possible to estimate the product particle size distribution of the Vertimill pilot scale from breakage parameters determined from a lab-scale batch ball mill. These results confirm that the Vertimill and the conventional ball mill use similar mechanisms of impact and that the main difference between them is the intensity and frequency of the impacts.

dynamic simulator of a rougher flotation circuit for a copper sulphide ore - sciencedirect

This paper presents a dynamic flotation simulator intended for designing and testing automatic control strategies, for evaluating the transient behaviour of the flotation process, and for training purposes. The simulator is based on a non-linear dynamic model that is derived from phenomenological and empirical relationships. It incorporates a new way of representing the loading of the bubbles with the various mineral species considered. The simulator was designed for a particular flotation circuit and was fitted with plant data in order to reproduce the plant behaviour both qualitatively and quantitatively. Both identification and validation data sets were used. Model dynamics had to be tested using ARMAX type models identified with plant data, due to the highly stochastic characteristics of the process. Plant and simulator responses were compared in steady-state and in transient conditions using these models. Results indicate the simulator is adequate for the stated purposes.
