About Intec Ltd

Intec Ltd is an Australian company which owns the Intec Process for superior and sustainable metals production. The Intec Process comprises a set of patented chloride-based hydrometallurgical processes that have been demonstrated to produce high purity base and precious metals from concentrates of sulphide and oxide ores, tailings and industrial wastes. The Intec Process has substantial environmental and cost advantages over both the widely used conventional smelting and refining processes and other known hydrometallurgical processes.

Intec: Looking at Waste With a Fresh Perspective
Intec is a world leader in the field of chloride hydrometallurgy with an
extensive portfolio of international patents. Intec is successfully applying its
technology to the recycling of heavy metals from industrial wastes in Australia.
Intec is using its technology, know-how and infrastructure for the recovery of
base and precious metal products from a wide range of mineral and industrial
resources.

Why Be Wasteful With Waste?

• In many cases , the defining aspect of a waste is not its chemistry or its physical features , but its provenance . • Mineral ores come out of the ground as highly impure mixtures. • They can contain very low levels of the desired metal. • As example, the gold industry mines one tonne of ore to recover as little as one gram of gold, or up to seven tonnes mined if you count typical overburden ratios.

• • A typical copper ore might contain 1% metal, so that the tonne of ore is worth $80 before mining, milling, flotation, transportation, smelting and refining costs are taken into account.

• • A typical zinc ore might contain 8% metal, worth $160.

• • Many inorganic industrial wastes can contain at least this much value per tonne , or considerably more . • The difference: provenance and volume. • When a metal-bearing material is produced as an unintended by-product than a deliberately sought product, it is highly regulated.

• • This leads to wasteful thinking.

Disposing of These Materials is Truly Wasteful
Economic cost
• Treatment and stabilisation/immobilisation fees
• Fresh stabilisation/immobilisation reagents, ‘bulking out’ the waste
• Transport of ‘bulked out’ mass
• Landfill gate charges for ‘bulked out’ mass
• Government levies for ‘bulked out’ mass
• Permanent loss of contained economic value $
Environmental cost
• No stabilisation technology is permanent
• At best, stabilisation/immobilisation simply slows the release of the metals
• Recurrent local community issues affect all landfills to some extent

Recover the value
It is much better to recover the metals
• No environmental legacy
• Massively reduced quantity and hazard
• Zero waste options for some ‘waste’ types
• Offset the costs using the contained metal value
• Potentially valuable by-products
• Environmental, ethical, intellectual and economic benefit

CASE STUDY: Spent Pickle Liquor Recycling at Intec Envirometals’ Research Facility in Burnie, Tasmania

==> picture [560 x 303] intentionally omitted <==

==> picture [168 x 28] intentionally omitted <==

Current Project: Galvanizing Industry Wastes

• Steel is dipped in hydrochloric acid prior to hot dip galvanizing

==> picture [168 x 91] intentionally omitted <==

• Over time, the acid strength decreases, and the acid builds iron, zinc and other contaminants

• This ‘spent pickle liquor’ (SPL) is conventionally disposed of as a waste, by first precipitating the metals with alkali, then dumping the heavy metal waste in landfill

• Intec has proposed a cleaner, cheaper zero waste alternative process to recycle the metals and acid back into useful products

SPL Recycling Project: Collaboration and Support

• This project is a direct result of an introduction made at EPA Victoria ’ s HazWaste Expo in November 2008

==> picture [157 x 91] intentionally omitted <==

• A typical industrial company with a waste disposal issue: GB Galvanizing Service Pty Ltd (GBG), one of Victoria’s largest galvanising companies

• A company with a technology solution: Intec Ltd

• Intec is working with GBG as our Victorian project partner to deliver an SPL recycling plant at GBG’s Dandenong site

• EPA Victoria is contributing $780,000 from the HazWaste fund to GBG

• Total p ro j ect cost estimated at ~$2.85 million

==> picture [157 x 52] intentionally omitted <==

• The project is being implemented through three stages:

• Phase 1: Pilot plant trials

• Phase 2: Semi-commercial demonstration plant trials

• Phase 3: Commercial plant construction and operation in Victoria

==> picture [481 x 37] intentionally omitted <==

==> picture [560 x 102] intentionally omitted <==

SPL Recycling Project: Stage 1

• Continuous pilot plant trials: November 2009 to February 2010

• Provisional patent lodged

• Key outcomes: • Tested a range of operating variables in order to frame the key operating parameters for the technology.

• 175 hours of operation, during which 289 litres of spent pickle acid were recycled.

• Successfully demonstrated both the recovery and electrowinning of zinc metal product, and also iron separation and recovery.

SPL Recycling Project: Stage 2

• Intec is currently working on Phase 2 semi - commercial trials

==> picture [193 x 91] intentionally omitted <==

• First trials November to December 2010

• These trials proved the technology at the commercial scale

• Engineering data generated for materials of construction and process optimisation

• New equipment ordered and installed

• Second trials commenced 21 February 2011 to demonstrate the reliability of the equipment

• Operations may continue after the current trial is complete:

==> picture [193 x 47] intentionally omitted <==

• Continue to yield engineering data

• Continue environmentally superior outcomes for interim SPL generated until the commercial plant is built

• Generate products for GBG’s reuse

• Generate by-products for sales evaluation

• Subject to commercial considerations and regulatory approval

==> picture [481 x 19] intentionally omitted <==

==> picture [560 x 102] intentionally omitted <==

SPL Recycling Project: Stage 3

• The final phase of the project involves the construction of a full - scale commercial facility at GBG’s Dandenong site

• Recycle a minimum of 1,000,000 L per year of SPL

• Avoid a minimum of 1,700 tonnes per year of liquid waste generation

• Avoid a minimum of 600 tonnes per year of solid waste disposal to landfill

• Generate a minimum of 70 tonnes of zinc metal per year for reuse by GBG

• Generate fresh acid for reuse by GBG in the pickling bath

• Generate iron and calcium by-products for industry use

• Victoria produces approx . , 3 000 , 000L per year of SPL . Is there a market opportunity for a larger plant capacity?

• Economics:

• The plant is competitive at 1,000,000L per year vs current disposal costs

• At 3,000,000L per year, modelling says that it would change the market

SPL Recycling: Future Opportunities

• Spent Pickle Liquor is a waste that is common to the galvanizing industry , domestically and internationally

• • Within Australia: • GBG has 117 m[3] of zinc bath capacity, and produces ~1 MLpa SPL • Victoria has ~286 m[3] of zinc bath capacity, and produces ~3 MLpa • Australia has a total of ~1,400 m[3] capacity

==> picture [157 x 91] intentionally omitted <==

• An estimate of total Australian SPL might be ~12-15 MLpa SPL

• • Are there opportunities in other states, particularly NSW & Queensland?

• Internationally:

==> picture [429 x 29] intentionally omitted <==

----- Start of picture text -----

• European markets favour zero-waste technologies
• Intec has already received international enquiries about the developing SPL recycling technology
----- End of picture text -----

• Europe, USA and Asia (particularly the growing China & India galvanizing industries) might be huge potential markets

Industrial Ecology

==> picture [560 x 185] intentionally omitted <==

----- Start of picture text -----

Industrial Ecology promotes enhanced sustainability by stimulating
innovations in the reuse of waste materials. The wastes or by-products of one
industry are used as inputs in another industry, thereby closing the material
loop of industrial systems and minimising waste.
Intec is pleased to be part of the Industrial Ecology Network, an industry-
driven initiative as part of the Waste Management Association of Australia:
“To promote and encourage the development of activities, processes and
relationshi p between entities which convert sur p lus , s p ent or unwanted
materials, energy and services into valuable resources.”
