S.H.O.T. - Selective Heat Ore Treatment

S.H.O.T. microwave technology is an electric-based, non-mechanical treatment comminution solution.

Overview

Novel S.H.O.T. Technology

As ore bodies age and grades decline, increasingly higher embodied energy input is required for comminution (grinding) to liberate minerals and maintain production, which both increases costs and the carbon footprint of these operations. It has been said that comminution consumes up to ~4% electrical energy globally, such that any significant reduction in this energy usage will have tremendous environmental impact.

S.H.O.T. microwave technology is a unique pathway to impact these challenges.

Solution

The S.H.O.T. Solution

What can be claimed as the most significant breakthrough in rock fracturing since the HPGR, S.H.O.T. microwave technology uses electric-based, non-mechanical comminution treatment as a pathway to significant energy reduction and enhanced mineral recovery in mineral processing. The fundamental technology partnership between Jenike & Johanson and Crescend combines solids handling and microwave technology expertise to commercialize this exciting technology in the market.

How does it work?

Microwave energy that is typically in the range of 0.3 to 3 kWh/t impacts a flowing ore stream. Differential heating results in fracture at the rock mineral-grain interface, effectively liberating the valuable mineral more efficiently and effectively.

Is it proven?

Both the microwave and bulk solids technologies have been well proven both in the theoretical world and in practice at a 150 tph pilot scale.
