Workshops

Workshop 1: Gold Recovery without Cyanide
Workshop 2: Dewatering and Dry Stacking of Tailings
Workshop 3: Lithium Ore Processing

Pre-Conference Workshops 1 and 2

Sunday 10th September 2017

Both will be interactive open forum workshops. 4 or 5 critical topics per workshop will be briefly introduced by well-known experts who have experience with various alternatives, then the topic will be opened for discussion by experts and participants for up to 45 minutes per topic. Issues for discussion are invited from those attending. We encourage attendance at both W1 and W2 as the alternatives to cyanide economically require leach solution recovery and recycle, which is relevant to W2. There is an attractive discount offered for those who wish to attend both. Lunch is included for both to encourage networking and sharing of information to continue. For both workshops we can (for the whole or part of the workshop) invoke The Chatham House Rule, to encourage the open sharing of information.

Workshop 1: Gold Recovery without Cyanide

8.30 am – 12.30 pm

This workshop will examine the impact of changing legislation and regulation as external drivers of technical change in mineral processing and extractive metallurgy, specifically focussing on cyanide and what this would mean for the gold industry. What are the options for gold recovery in jurisdictions where cyanide is banned?

What are the consequences resulting from the various alternatives?

Processes to be considered include the use of Thiosulphate, Glycine, Bromine and Bromide, and other lixiviants. Related topics might include zero discharge, site remediation and treatment of hydrocarbon contaminated material. Participants who have experience with these or other reagents, or a case study to present, are invited to contact the MetPlant Convenors.

The workshop will be facilitated by the MetPlant Convenors with the assistance of Rob Dunne.

Workshop 2: Dewatering and Dry Stacking of Tailings

1.30 pm – 5.00 pm

This workshop will broadly encompass the theme of Rob Dunne’s Distinguished lecture later that evening titled Water in mining - facts, perceptions and conflicts.

The workshop will be facilitated by the MetPlant Convenors with assistance from David Brett. Topics will include preferred methods of dewatering, including gravity thickeners, filtration and dry stacking requirements compared with tailings dams. Tailings dams have been a continuing cause of concern, for design, construction, seepage, short and long term management, weather events and failures, but when well designed and managed tailings dam are safe and dry stacking is not the magic bullet to solve all tailings issues.

Dry stacking of filtered tailings are likely to become more common as water resources become scarcer, but benefits can be achieved in other ways from slurry tailings in appropriate climates by water management and solar drying or mud-farming.

Participants who have a related case study to present, are invited to contact the MetPlant Convenors.

Workshop 3: Lithium Ore Processing

Wednesday 13th September 2017
8.30 am – 5.30 pm

This one-day course examines the current state of the processing of lithium ores to a battery‚Äźready product and is aimed at minerals industry professionals who wish to gain a greater understanding of the processing principles and practices as applied to lithium ores.

The topics covered include an overview of why there is demand for lithium, lithium geology, comminution, coarse and fine particle separation methods, typical flowsheets, conversion of concentrates and a summary including some specific things to be aware of. The workshop is primarily about hard rock resources but also has an overview of brine resources and processing.
