  "definitions": [
    "A method of alluvial mining that recovers heavy minerals from the sands and gravels of a stream bed. The process involves excavating the deposits and using water to wash away the lighter sediment, allowing the denser valuable minerals, such as gold or cassiterite (tin ore), to be concentrated and collected. This technique relies on gravity separation and is often carried out using equipment like sluice boxes, pans, or rockers.",
    "An ancient or historical method of mining alluvial deposits, typically for tin or gold, by diverting a stream or river to wash away overburden and expose the valuable minerals. This technique involved constructing channels, dams, and sluices to control water flow. Streamworks were common in regions like Cornwall, England, for tin extraction."
