indicator plants growing on gold ores

Operational review | Sustainability | Annual reports 2013 | Sibanye Gold

Similar to No 2 plant, ore is received from surface rock dumps by rail and truck. The plant has four SAG mills followed by cyanide leaching and CIP. Loaded carbon from No 2 and No 3 plants is trucked to plant and processed at the central elution and smelting facility. Further upgrading of the No 2 plant is planned for 2014.

1. Soils & Plant Nutrients | NC State Extension Publications

An ideal soil for plant growth contains 50% pore space and 50% solids, with the pore space filled with equal parts air and water. This distribution rarely occurs because pore space varies with soil texture and soil management. For example, tilling increases pore space, while poor drainage and compaction reduce it.
