A paddlewheel ensured a constant source of water. Again gravel was shoveled into the top end and the water pushed it along a long wooden course, sometimes hundreds of feet long. Again, the slats collected the heavier ore, which was then further processed. For these early techniques, water was an essential part of the process.

· Heap leach mining is an industrial hydrometallurgical process, where the metal contained in an ore body is extracted by dissolution. The target mineral is leached with an aqueous solution whereby the mineral is dissolved into what is called a "pregnant" solution which, is then captured and later recovered downstream in the processing line.
