What this report found

A framework for planning land use on rehabilitated coal mining land, built from a review of international and national regulatory and corporate guidance and from interviews with industry practitioners. The review found that existing guidance requires land to be returned as close as possible to its pre mining condition, while community needs are pushing rehabilitation towards alternative land uses that can sustain livelihoods.

What this report found

A pilot brine concentrator treated Stage 3 reject effluent from a mine water reclamation plant, raising total dissolved solids from 24 g/L to 154 g/L at 88 per cent water recovery. The condensate met the national potable water specification. A separate run concentrated brine from 76 g/L to 145 g/L, solid salts were precipitated, and no scaling or fouling was seen.

What this report found

Coal can feed products well beyond combustion. The study sets out routes to rare earth elements held in particular seams, building materials made with carbon fibre and carbon char, coal foam and graphene composites, carbon black and activated carbon, including a coal derived activated carbon reported to hold four times the gas of compressed natural gas at lower pressure.
