J.G. Carton, A. Baroutaji, in Reference Module in Materials Science and Materials Engineering, 2016 2.3 Flow Field Layout. A serpentine flow channel, Figure 2, is one of the most common and practical channel layouts for existing PEM fuel cells and it is often referred to as an industrial standard.Continuous fluid flow through the channel forces the reactant to flow over the entire active area ...

Selected papers from the conference have been published in Volume 103-104 (April 2017), a special issue of Minerals Engineering. The papers can be viewed and downloaded at ScienceDirect. Prof Malcolm Powell has kindly given us permission to publish his keynote presentation: "Comminution modelling in the context of integrated process prediction".

Comminution due to faulting causes activation of fault rock surfaces, such as the production of reactive radical species. In this study, we report on the generation of H 2 O 2 by immersion of comminuted sedimentary, igneous, and metamorphic rocks that are broadly representative of those present at a variety of depths in subduction zones.

First Published: 07 April 2014. The air‐core is one of the most important flow characteristics in hydrocyclones. Air‐core profiles were measured by a dual‐plane fast‐response electrical resistance tomography system and high‐speed camera. The influence of design and operating conditions of the hydrocyclone on air‐core size is studied.

Processes will differ with Ni-rich olivine/serpentine vs lower-value basalts 4. Could electrochemical mineralization approaches reduce or eliminate comminution? Perhaps lower the C footprint of generation of acids/bases, regeneration of redox reagents ex situ, but the scales needed may differ by orders of magnitude. 5.

Comminution costs include power, grinding media and maintenance materials. These costs represent 30% of costs for the 1 Mt/a plant and over 50% of costs for the 20 Mt/a plant. Thus, the "efficiency" of a modest plant is improved by simplifying the comminution circuit and reducing labour requirements. Improving the grinding efficiency of the

Extracting CO2 from mine rock to mitigate climate change. Dr. Erin Bobicki, a chemical engineering professor at the University of Toronto, is researching how to remove CO2 from nickel ore and to use mine tailings capture carbon from the environment. Bobicki was part of a recent Northern Ontario innovation event sponsored by the Ontario Chamber ...

Comminution of the serpentine particles remains important as the SEM–EDS results support the concept that magnesium is only being removed from the particle surface. The concentration of magnesium in the bulk remained significantly higher than in the surface for each of the samples tested.

Carbon Engineering's pilot plant currently ... some other minerals, such as serpentine, can also release substantial amounts of Mg 2+ due to their high surface area. Labile magnesium is ... catchment-scale kinetics seem to be far slower than the lab-based ones. If faster reaction rates occur, less comminution of rocks is needed. ...
