Heron Resources’ Woodlawn zinc-copper project in the New South Wales, Australia, is really starting to take shape, with the company taking delivery of an IsaMill™ (pictured) earlier this week.
The mill is an important part of the company’s processing plant, providing the fine grinding capability to reduce the flotation feed to 30 microns in size. It will treat zinc rich reclaimed tailings, as well as polymetallic primary ore in different processing modes.
The 3 MW 10,000 IsaMill comes with an IsaCharger™ media delivery system, as well as commissioning services from Glencore Technology. It will be the 50th M10,000 installation.
Heron’s Managing Director Wayne Taylor said: “The arrival of the IsaMill marks the step change in technology to be applied to the Woodlawn zinc-copper project. This technology only became available after Woodlawn’s former operations (which stopped in 1998) and it enables Heron to reduce the grind size to provide the most effective mineral liberation, allowing for the highest recoveries to our base metal concentrates.”
The IsaMill is manufactured in Germany and first entered commercial use in 2000.
In the meantime, Heron’s EPC contractor, Sedgman, continues to make good progress with overall construction of the project, reporting the development as 62% complete at the end of June.
The project remains on schedule for the commencement of commissioning in the December quarter.
Woodlawn has an annual steady-state production target of some 40,000 tonnes of zinc concentrate, 10,000 t of copper concentrate and 12,000 t of lead concentrate, along with associated gold and silver.
