Gold phytomining in arid and semiarid soils. - CAB Direct

Metals such as gold, copper and lead can be found in soil at high concentration at many desert locations. However, adverse weather conditions, specifically a lack of moisture, limit the range of applicable technologies to recover these metals. A number of plant species have been tested under both laboratory and field conditions to determine their potential for use in the

Phytomining of gold: A review - ScienceDirect

2013-5-1  Phytomining of gold involves extracting gold from soil substrates by harvesting specially selected hyperaccumulating plants. Phytomining has potential to allow economic exploitation of low grade ores or mineralized soils that are too poor for conventional mining of metals. Gold is the most promising option for phytomining as its market value is ...

Gold mining is a tremendously important economic activity in rural districts of Ethiopia. We assessed the impacts of artisanal gold mining on soil and woody vegetation in northern Ethiopia. Estimation of soil loss, plant inventory, group discussions and transect studies were used to address the research questions. We employed t-test to compare woody species and soil loss between mined and ...

Is Soil A Renewable or Nonrenewable Resource?

2020-9-7  In arid and semiarid areas where there is no enough water, replacing the lost water becomes a problem. That makes it more of a nonrenewable resource. Soil water is mainly gotten from the aquifer when it gets depleted at a faster rate than it is recharged; therefore, water becomes nonrenewable, which in return cannot renew the soil.
