A Whole System Approach to Innovation• Embrace macro heterogeneity

• Design for coarse separation • Blasting, conveying, ore handling…• Crushing, grinding, flotation

• Simulate and optimise whole‐of‐stream

• And design for microtexture

• Develop measurements• and accept measurement shortfalls

• Supporting management systems• Align culture, KPIs

Simple technology ? 

A Conservative Industry? 

Crossing The Innovation Chasm ?

A Tale of Two Innovations

INNOVATION 1 INNOVATION 2

Concept from unrelated industry 

50 times scale up, batch to continuous 

Enthusiasts over‐ruled conventional theory

Complex piloting

Significant capital

Increased operating cost and complexity

No pre‐existing site or supplier skills

Would add significant value if delivered.

Concepts and references from mining

No new equipment

Strong theoretical base

No piloting or capital

Reduce operating cost, simplified operations

Use existing site skills

Would add significant value if delivered

A Tale of Two Innovations

Seven necessary conditions

1. A driving need

2. Designed for your ore

3. Passionate champions

4. Bite‐sized implementation

5. Simple IP rights

6. High quality ongoing support

7. Enabling organisation

Aligning the conditions for innovation
