Project Objectives – to be “1st to be 19th”
• Lab scale HAC & Demonstrator scale HAC – Year 1– Cheap compressed air for mining operations
– Obtain OPA certification as energy efficient
– Prove applicability for deep mine cooling
– M&V activities at demonstration scale
– Establish / prove supply chain
• Marketing and Commercialization – Year 2, onwards– Pneumatic power for mines
www.mirarco.org
– Pneumatic power for mines
– Air separation systems
– Advanced products
• Innovation program – Year 2 & 3– Compressed air yield enhancement
– Carbon capture
– Refrigerant compression
– Tower block air conditioning
– Autoclave mineral processing

Why are you here?
• Project procurement ‘flurry’ between May & Oct 2015
• Not particularly specialist parts
• Project brief to stimulate business activity
• Need to establish and prove HAC supply chain
• Preference to procure locally
www.mirarco.org
• Preference to procure locally
• We undertake to ensure that general contractor will inform you of procurement processes, for items on which you have expressed interest in supplying
• Ultimately, procurement decisions will have to be based on lowest cost meeting specification

Ragged Chutes, the largest ever HAC, produced 40,000 cfm @
120 psi(g) (22.7 kg/s @ 8.3 bar(g)) but is now derelict

The Atlas Copco GT153 installed in a Chinese steel mill produces
322,500 Sm3/h air at 6 bar(a) (190,000 cfm @ 87 psi(a) )
