Case Study: Gold producer chooses Luhr for Randall’s Gold project

Supplier: Luehr Filter Australia Pty Limited
04 November, 2011

As part of its new Randall's Gold Project, Integra Mining installed a large crushing and screening plant.

Background

  • Company: GR Engineering/Integra Mining Ltd
  • Location: Kalgoorlie, WA
  • Flow rate: 34,600 Am3/h
  • Temperature: 25°C
  • Industry: Mining - Gold

Problem

As part of its new Randall's Gold Project, located around 60 kilometres southeast of Kalgoorlie, Integra Mining installed a large crushing and screening plant.

This part of the process produces by far the largest amount of dust, which if left untreated, could cause a major environmental problem.

Solution

To address this issue an integrated dust extraction system was designed to capture the dust and return it to the process -- this was achieved by the installation of a Luhr DF Fabric Filter.

The unique feature of this design is its flat horizontal filter bag arrangement, which allows extremely quick and safe inspection of the clean air chamber and bags.

This design eliminates the need to use tools or lifting gear to access the filter bags.

Bag changing can be conducted from the generous adjacent access platform and does not require maintenance personnel to enter the filter.

As with most Luhr designs, the filters used on this project are based on a modular concept. This allows the filters to be fully assembled with filter bags, pulse cleaning system and electrical controls.

The complete unit can then factory tested prior to shipment which not only ensures the filter is fully functional on arrival at site, but also greatly reduces site installation errors, time and labour.

Result

The unit was supplied on schedule and from information received from site is achieving excellent dust control.
