    Hi Everyone,

    My name's Andrew, I worked on the former sulphide site in 2004-5 capping the slag piles with plastic. I remember a lady taking photo's of pretty much the entire plant shortly before the structural demolition commenced, I was told they were for historical purposes but can't remember if she represented NIHA? Ross from Pasminco took a few of us on a brief walk through the plant (which was fascinating) but I didn't have a camera with me.

    My primary reason for working on the site was simply to have a look inside the place and see how it all worked. I had always loved looking at the place in awe from the carpark since i was a young boy.

    I'm wondering if anyone might have some pictures from inside the plant that you might be prepared to share with me for private viewing? or is there anywhere that I might be able to view or purchase the pictures that the lady took? (must have been hundreds of them taken) Maybe you might be the person i'm referring to?

    I'm especially interested in the Acid plant, Sinter shed and Lead/Zinc refineries.

    I ceased working on the site and moved to Melbourne about the time the wrecking machines went to work, so any demolition pic's of the place would be very interesting also...

    My only momento from the Sulphide works is one of the pushbikes that were used around the place by the workers, I still ride the thing - complete with it's crust of grey residue. Does anyone else have one too??

    Any assistance and/or feedback regarding my search for any pictures from inside the place would be very much appreciated.

    Thanks for your time reading this post...

    Kind Regards,


    The smelter bought out 3 cd when they finish up try Pasminco.

    Andrew your info has been sent to NIHA members, did you look in the Media Gallery Mr. Green

    The Sulphide

    Much of northern NSW was underdeveloped when the management of a London-registered company known as the Sulphide Corporation (Ashcroft’s Process) Limited set their sights on establishing an industry in 1895. They were confident they could make a commercial success of the electrolytic zinc process developed by Edgar Ashcroft.

    Although the first industrial use of the Cockle Creek site failed after just two years, it left behind two important legacies. First, it advanced the electrolytic process significantly, paving the way for successful electrolytic zinc plants like the EZ Plant in Hobart (now Pasminco Hobart Smelter). Secondly, it began a remarkable period of industrial activity at the Cockle Creek site, which spanned more than a century.

    The site has been through enormous change in its 106 year history – World Wars, the Great Depression, population growth, market fluctuations, changes in process, a myriad of different products, and most recently, community and environmental concerns. It grew to be one of the Hunter’s largest employers (at one time employing more than 800 people) and an important economic contributor (in its last year of operation, it contributed more than $80 million to the local economy).
    1895 Sulphide Corporation chooses Cockle Creek site for electrolytic zinc plant
    March 1897 Plant operations commence
    July 1897 Electrolytic process abandoned – decision taken to convert plant to an orthodox lead smelter

    1917 Full-scale lead refinery constructed and commissioned
    1922 Smelting section of the plant closed due to low metal prices
    1923 Expansion of acid and fertilizer production
    1923 Six Barrier Roasters erected to roast zinc concentrates – gases converted into acid in Chamber units, calcines shipped to EZ in Tasmania
    1925 Sulphide Corporation entered its cement production phase
    1931 Company directors and salaried staff agree to 20 % wages cut to minimize costs in the wake of the Great Depression

    Sept 1949 $3 million upgrade announced to double sulphuric acid production and to enable zinc production by the ISF (Imperial Smelting Furnace) process
    1950 Sulphide Corporation Limited enters voluntary liquidation, and a new company is formed - Sulphide Corporation Pty Ltd, a wholly owned subsidiary of Consolidated Zinc Corporation Ltd.
    1957 Plans announced for an $8 million upgrade to re-establish zinc smelting operations, and expand sulphuric acid and superphosphate plants
    Aug 1961 New zinc-lead smelter commissioned at Cokle Creek, ushering in new era of employment, export revenue for both the company and the Port, and 40 % boost in Australia’s zinc-lead smelting capacity
    1962 Conzinc Riotinto takes 75% control of Sulphide Corporation
    1964 Corporation founds a subsidiary, Greenleaf Fertilisers Ltd, to manage fertilizer production at the plant
    1965 Greenleaf begins construction of a $16 million high-analysis fertilizer plant at Kooragang Island ( the first manufacturing plant on Kooragang)
    1968 Refinery added to zinc smelter, adding four new products to plant output
    1970 Sulphide sells its interest in Greenleaf to Australian Fertilisers Ltd, ending 56 years of involvement in the industry

    1997 $8 million Tail Gas Scrubber constructed, significantly reducing sulphur dioxide emissions
    2001 Business Improvement process (BOOM) introduced to Pasminco smelting sites as part of a company wide effort to deliver $100 million in cash savings in a 12 month period
    2002 Despite significant improvements, Pasminco announces closure of the site between 2006 and 2008 due to long-standing marginal performance
    2003 Closure is brought forward to September 2003 because of the negative movement in key external factors since the original announcement
