Black Sand Collection from Rain Drainage Systems

Heavy rainfall brings iron particles into local waterways through runoff, where they accumulate naturally along stream beds. These areas have been studied for their mineral content, specifically targeting the collection and processing of magnetite to extract gold from them.

Important Terms:

• Iron Particles: Small fragments or grains composed primarily of iron.

• Runoff/Water Run-off (or Drainage): Water that flows over land surfaces into streams after precipitation events like rain.

• Magnetite: A type of iron oxide mineral known for its magnetic properties, often used in mining to separate valuable minerals from less useful material through a process called ‘magnetic separation.’

• Gold Extraction/Recovery: The various processes involved in removing gold particles or compounds from ore and other materials where they are found."
