The best types of products for small-scale production are those that have a high 'added-value' as well as a good demand. A high added value means that cheap raw materials can be processed into relatively expensive products. It also means that this can be done at a small scale of processing using equipment that is affordable.

Gold processing - Gold processing - Mining and concentrating: The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then piled into heaps for ...
