OverviewOverview

LeachingLeaching

• Titanium Provides Superior Corrosion Protection

• Outer Steel Provides Strength

• Clad Construction Titanium Alloys can be Selectively Applied in Specific Regions to Maximize

Performance

• Low Maintenance and Long Vessel Life SpanAutoclaveAutoclave

LeachingLeaching

Option 1:Pure Oxygen

• Explosive substance• Need for storage• Purchase and Transportation costsOption 2:

Air Purification• Expensive Equipment• Extracts only 93% oxygenOption 3:

Air• Direct and Free Source• Nitrogen and Argon Gases are Inert• No Need for Storage

LignosolLignosol

Liquid:

• Difficult to Store and Transport

• Requires Extra Storage Equipment

• Abundant in Amount

• Less Expensive; Less Purity

Powder:

• Storage and Transportation Easily Manageable

• Limited Availability

• Expensive; High Purity

Counter CurrentCounter Current

ThicknersThicknersHigh–Rate Thickners

• Settling solids quicker

• Achieving quicker underflow density

• Reduction in space environment

• Separation more than 20 times more effective

• Cyclical designs provide long operation life

Counter CurrentCounter Current

Epoxy-Coated PipingEpoxy-Coated Piping

• longer lasting operating time

• cost efficient material

• lower handling costs

Waste ManagementWaste Management

• Produces Needed Sulfuric Acid

• Helps Reuse the Sulfur Rather Than Disposing of it

• Generates 1435.8 kW/h of Electricity to Run the Plant

• Selling the Sulfuric Acid Would Generate a Profit of $0.9 million Annually

Sulfur RecyclingSulfur Recycling

Waste ManagementWaste Management

• Allows Another Company to Use Our Waste for their Benefit

• Less Waste Would Go to the Tailing Pond

Selling Ferric OxideSelling Ferric Oxide

ElectrowinningElectrowinning

• Eliminates Any Organics Through Vigorous Filtration

• Reduce Lead Contamination

• Titanium Cathode Bus Bars, Contacts

• Intend to Upgrade to Titanium Cathodes in Future

Flow ChartFlow Chart

ElectrowinningElectrowinning

• Plant is Completely Mobile

• Tanks are Arranged So that Further Addition of Tanks is

Possible

Plant Flexibility and MobilityPlant Flexibility and Mobility

ElectrowinningElectrowinning

• Easiest Way to Extract Silver from Sulfuric Acid Solution

• Silver is Extremely Pure When Collected on Cathodes

• No Extremely Large Additions to the Plant (Just a Few More Electrowinning Cells)

Silver RecoverySilver Recovery

ElectrowinningElectrowinning

• Heap Leaching Used for Low Grade Ores at Reduced Cost

• Less Tailing Pond Wastes and Solid Liquid Separation Steps

• Merrill-Crowe has Lower Costs Both Capital and Annual

• No Need to Concentrate Solution After Leaching

• Cyanide Solution Can be Recyled in Merrill-Crowe but Not in Other Processes Such as Carbon in Pulp

ConclusionConclusion

•Environmentally Friendly, Wastes are Converted into Potential Profit

•Promoting Continuous Employee Safety

•Benefit for the Mining Industry

•Setting Benchmarks in Copper Production
