Topic: Coldry & Matmor
Abstract: The Coldry technology is a patented brown coal densification and pelletisation process that changes the naturally porous form of brown coal to produce a dry, dense, energy-rich pellet. Coldry technology will be utilized in the integrated demonstration plant as an efficient pelletisation process to supply composite Iron ore and lignite pellet feed for the Matmor process. Matmor is a technology for the production of High Quality DRI. The process operates at relatively low temperatures and is highly energy efficient. Utilizing novel reduction chemistry, the Matmor process has a favourable carbon intensity generating significantly lower CO2 emissions and a substantially lower water consumption while still producing high-quality DRI compared with conventional Iron making technologies. Given the utilization of low-rank coal and iron ore fines and reduction of CO2 emissions, feasibility studies indicate promising project economics with both CAPEX and OPEX advantages.
