A Globally Accessible Event 

The Mining Cleantech Challenge efficiently provides targeted connections between mining industry operators, OEMs, and clean technology solution providers with a mutually beneficial goal of meeting industry’s needs while at the same time introducing innovative solutions to the marketplace.

Innovative solutions providers will complete a competitive vetting process, after which 10 – 12 companies will be invited to present their technologies to the partners and sponsor/judges .

There are no geographic restrictions or requirements for participating companies.

Applications open January 28.

 

2020 Mining Cleantech Challenge Recap

In Partnership With:

Mining companies are looking

for the following technologies:

ADVANCED MATERIALS AND CHEMICALS

(including but not limited to): Novel materials or chemicals comprised of no or fewer hazardous chemicals; advanced materials less likely to rust or corrode which will improve containment; improved treating chemicals and detection methods; chemicals to extract hazardous items from produced fluids; new products made from captured CO2, new ways to capture/separate CO2 and NGLs.

BIOLOGICAL SOLUTIONS

(including but not limited to): That target microbes or enzymes to treat waste or advance traditional mining extraction processes.

BLOCKCHAINS

(including but not limited to): Blockchains are an immutable, distributed database that opens up new use cases between trust boundaries, such as between disparate organizations. Applications of blockchain technology in mining could include the creation of efficient, trusted marketplaces; or distributed transactional platforms that can provide value in many areas of the business (such as compliance, CSR and social engagement, supply chain efficiency and tracing, and commodity trading). A recent example is the creation of a consortium involving Shell, BP, and Statoil who are working on the development of a blockchain-based energy commodity trading platform, along with three large commodity traders. The common thread found in most emerging blockchain based solutions is increased efficiency between boundaries of trust- either through disintermediation of 3rd parties or by enabling the digitization of cross organizational processes.

(including but not limited to): Numerous methods exist for the destruction of free/WAD cyanide complexes (e.g. Caro’s Acid, hydrogen peroxide, CuSO4-SO2, SART) from spent process solutions prior to discharge into a tailing storage facility. Looking for novel equipment design, chemical additions, resins, etc. that result in lower overall cost-of-operation (from consumables, manpower, maintenance, regenerated cyanide for reuse in the operation) and/or improved safety for operating and maintenance personnel.
