Processing Track: Mineral Processing, Refining and Recycling

How rock becomes metal and old batteries become new ones: crushing, separation, leaching, lithium, recycling and the lockout and confined-space rules that keep plant crews alive.

Processing covers mills, refineries, battery plants and recycling lines.

4 modules · about 90 minutes in all · a quiz after each module · final test: 12 questions, pass with 10 right

What's in it

  1. Module 1: Crush, grind, separate

    Ore comes out of the ground as rock with a small amount of valuable mineral locked inside.

    About 15 minutes · quiz of 5 questions on this module · sources include USGS and USGS Mineral Commodity Summaries

  2. Module 2: Leaching, electrowinning and lithium

    Some ores are processed with chemistry instead of flotation.

    About 15 minutes · quiz of 5 questions on this module · sources include USGS and USGS

  3. Module 3: Battery recycling

    Lithium-ion batteries hold lithium, nickel, cobalt, manganese, copper and aluminum.

    About 15 minutes · quiz of 5 questions on this module · sources include EPA and DOE ReCell Center

  4. Module 4: Plant safety: lockout, confined space, chemicals

    Plants are full of stored energy: motors, conveyors, pressurized lines, gravity and chemicals.

    About 15 minutes · quiz of 5 questions on this module · sources include OSHA and OSHA

The full lessons, quizzes and final test are open to crew members. Joining is free.

A question from module 1

What is comminution?
