Superior & Sustainable Metals Production

2. Company Overview
Intec International projects is an Australian company with patented
hydrometallurgical technology plus a range of know-how and infrastructure
for the recovery of base and precious metals from a wide range of mineral and
industrial resources.
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 mining companies on a wide range of Australian and
international minerals processing projects and recycling of heavy metals from
industrial wastes in Australia and worldwide.

3. The Intec Process
• A cheaper, cleaner alternative to conventional smelting for base metal
mineral feedstocks .
o Particularly low-grade, polymetallic and/or contaminated mixed
concentrates.
o High technology for recovering of metals from sulphiedic materials
o It also offers a non-cyanide alternative for gold-bearing concentrates.
• The Intec Process can produce valuable metal products from waste materials
that would conventionally be disposed to landfill.
• In many industrial waste recycling applications, the Intec Process can offer a
zero-waste recycling option.
Supported by over 200 international patents across seven patent ‘families’, the
Intec Process can extract and recover copper, lead, zinc, nickel, gold, silver and
other base and precious metals from a wide range of materials.

Processing minerals and recycling
industrial wastes
• Cyclic process
• Leach the metals into solution
• Extract by-products if appropriate
• Recover products as high grade metal
and/or chemical intermediates
• Highly flexible and adaptable to
various feedstocks

5. The Intec Process
Able to extract and recover metals from mineral feedstocks and industrial wastes
• Copper
• Zinc
• Lead
• Gold
• Silver
• Nickel
• Indium, scandium, molybdenum and other useful metals

6. Advantages of the Intec process
• Able to economically treat low grade mineral concentrates.
• Able to economically treat polymetallic concentrates in a single process.
• Able to recover by-product value from important minor metals contained
in concentrates.
• Able to economically treat contaminated feeds.
• Able to economically treat mixed base and precious metals feeds.
• Able to economically treat metal-bearing industrial wastes.
• The Intec Process residue is clean and environmentally stable.
• Operates at atmosphere pressure and at temperatures <100°C.

7. Intec Research
INTEC has experience and expertise across a range of technologies, applying the best
combination proven and cutting-edge technologies to suit each project that it
develops. Intec spent over US$70m advancing the technology to commercial
readiness.
The process and design engineering of team at Intec is able to provide process
flowsheet development, flowsheet modelling, in-house process evaluation testwork
(laboratory, piloting and demonstration scale), scoping/feasibility studies, and
financial modelling for hydrometallurgical minerals processing projects. Often a
combination of common base and precious metal hydrometallurgical circuits can be
combined with proprietary Intec technology circuits, for example the production of
zinc sulphate crystals would involve an Intec halide leach, solvent extraction, and
then crystallisation from sulphuric acid brine.
The team has gathered significant experience in testing and developing over 50
projects in the past 15 years, for gold, copper, silver, lead, zinc, nickel, cobalt, indium,
and platinum. The testing has focused on agitated leaching circuits, purification
techniques (cementation, solvent extraction, ion exchange resins, and precipitation),
and product recovery (electrowinning, sulphidisation, and precipitation).

10. Advantages:
Economical at small or large scale
Highly environmentally attractive
Low energy and low water consumption
No liquid effluent
Waste air, water vapor and carbon dioxide are scrubbed prior to venting
Same residue as copper process that has EPA licence
Highly tolerant of impurities – particularly manganese
Upstream savings – can treat low grade complex concentrates, facilitates higher metal recovery

11. Corporate Opportunities
Intec is currently seeking strategic partners to license unlock value from
mining and mineral projects opportinities
Our company can offer our partners:
• Intec’s innovative technology,
• Intellectual property,
• Know how,
• Project development expertise and
• High-class testing and demonstration facilities,
to work with companies with the financial and project resources to capture
and unlock value from mineral assets and industrial wastes that are currently
substantially undervalued.
