Mining gold has never been considered an environmentally friendly process. In order to get gold out of the earth, extremely toxic cyanides are sprayed on crushed ore to help with the extraction process. While effective, using cyanides regularly leads to environmental contamination, making this a less than ideal method of mining gold.
May 14, 2013· The new process also can be used to extract gold from consumer electronic waste. Current methods for gold recovery involve the use of highly poisonous cyanides, often leading to contamination of the environment. Nearly all gold-mining companies use this toxic gold leaching process to sequester the precious metal.
