Circular Economy and Mining - 2018 SME Annual Conference (Session Co-Chair and Presenter)

Dr Gavin Mudd and I will be co-chairing a technical session on the Circular Economy and Mining at the 2018 SME Annual Conference in Minneapolis, MN. Please let us know if you're interested in participating or attending.

The theme:

Consumer demands and innovation are driving the world towards a circular economy, where growth can decouple from resource and environmental constraints. The mining industry business model is mainly based on high volume ore treatment and waste production. How might the industry adapt and thrive in a shift to the circular economy?

The abstract for my presentation is:

The circular economy for metals currently centers around recycling/reprocessing smelter, refinery and semi fabricated wastes, and consumer scrap materials recovered from end of life sorting. Some mining companies are connected to the circular economy through integrated mine to refine value chains, while others are disconnected as they only produce mineral concentrates. How does industry structure influence how mining companies engage in or are affected by the circular economy? Will circular economy related government regulations and corporate sustainability targets change the economics, environmental and stewardship aspects of mined metal supply? The topic will be analyzed using the copper and lead/zinc industries as examples.

COM2017 Conference of Metallurgists, Energy and Eco-Efficiency in Mining and Processing Symposium, Vancouver (presenter)

Please let me know if you'll be coming to COM2017.

I will be presenting a paper titled: 

Integrated Mining and Processing Systems Design for Eco-Efficiency

The abstract is as follows:

The mining industry faces increasing economic, environmental and social challenges, as easier deposits deplete and ores become more difficult to mine and process; head grades decline; projects migrate to increasingly remote and difficult geographies; and the industry faces more stringent environmental and social standards. While these factors increase costs and risks, they also present opportunities for a more integrated approach to mining, processing, materials handling and waste management. Two key areas of risk are in tailings and water management. As mining and processing tonnage rates continue to increase, the disturbance footprints, water and energy consumption and scale of tailings storage facilities also rise. These factors can be mitigated by more selective mining, ore sorting and pre-concentration, and more intensive tailings dewatering. Such alternatives must be considered in conjunction with the selection of mining method, metallurgical flowsheets, major equipment selection, and key process design criteria. For example, increasing the grind size of a concentrator reduces energy consumption and eases tailings dewatering, but may cause challenges with metal recovery. Emerging technologies will be reviewed, and economic and environmental trade-offs for eco-efficient alternatives will be presented for metal sulfide mines.

Presentation to BERC - Strategic Metals in Batteries: Clean Tech Possibilities

  • Richard & Rhoda Goldman School, University of California at Berkeley (map)
  • Google Calendar ICS

I will be presenting on strategic metals in batteries to the Berkeley Energy and Resources Club (BERC). 

As momentum for environmentally friendly technologies grows, concerns have arisen about the supply of critical metals such as lithium and cobalt for batteries; tantalum in capacitors; indium, cadmium, selenium and tellurium for solar cells; and rare earth elements (REE) for wind turbines.

The geology and geography of mineral deposits can greatly affect the extraction processes, costs, quantities and security of supply. Some strategic metals are produced as by-products of base metals such as copper, zinc and nickel, which affects their economics. This BERCShop will discuss complexities and possibilities of such metal supply, and will include a case study on cobalt.

The presentation is open to all present and past BERC members, and the Eventbrite can be found here.

A summary copy of the presentation can be found here.

Canadian Minerals Processors Conference, Ottawa (attendee and workshop participant)

In the lead up to the CMP conference, Laurie will be attending a Natural Resources Canada workshop on water in mining to support a consulting assignment reviewing water recovery and reuse in base metals and gold processing plants. At the conference he is looking forward to technical talks on ore sorting and coarse particle flotation to save energy in processing, cyanide replacements and cyanide destruction to minimize environmental risks in gold processing, and catching up with several old colleagues.

A summary blog on the conference is available here.

Climate Council Fundraising and Kimberley Expedition

Laurie is currently fundraising for Climate Council of Australia to support production of independent and credible research and communication materials about climate change mitigation and adaption. At the end of the campaign, he will join Chief Councillor and author, Professor Tim Flannery, and other Climate Council fundraisers on an expedition to the Kimberley region in Western Australia. Laurie will pay for the expedition himself, all funds raised go to Climate Council. You can support the campaign here.

Carbon Talks: Levelling the Playing Field as Vancouver Implements its Renewable City Strategy (attendee)

What are the roles of equity, justice and democratic process as the City of Vancouver moves forward with its energy planning? 

According to the World Energy Council, energy equity is about accessibility and affordability of energy supply across the population. While cities are demonstrating climate and energy leadership, they will need to do so while ensuring affordability of renewable energy.

Vancouver has both an ambitious energy plan, as well as acute affordability issues. Is there a risk that greater use of renewable energy in the City of Vancouver will impose unequal economic burdens on different segments of the community? Could the energy plan compromise the City’s goals for social equity? What are the roles of equity, justice, and democratic process as the City moves forward with its energy planning?
