Workers involved in mining, quarrying or fishing are engaged in primary production. Primary production involves extracting or harvesting natural resources directly from the earth or sea, such as minerals, oil, gas, fish, and timber. It is the first stage of the production process, and it provides the raw materials for secondary production, which involves turning those raw materials into finished goods, such as steel, paper, or processed foods.

They play a crucial role in the economy by providing the raw materials needed for other industries to function.
