Background Typically a placer mine moves up-valley so that settling ponds and water runoff will be down gradient from the wash plant. Often the original stream is relocated to a temporary channel during the period of mining. In addition, the previously mined ground cannot be immediately reclaimed since it is necessary to maintain a drain […]
