Newlox's Cyanide Use in Costa Rica - A Global Contradiction Currently, Argentina,
Costa Rica, the Czech Republic, Ecuador, Germany, and Greece
have banned the use of cyanide in all gold and silver mining.
https://sacredland.org/lake-cowal-australia/ Costa Rica has banned cyanide. The ban was motivated by environmental degradation and a repeated failure to operate and control cyanide leaching facilities safely.

Costa Rica, Argentina, Germany, the Czech Republic, and Turkey,
have an outright ban on the use of cyanide in gold extraction throughout the country. https://www.researchgate.net/publication/335926799_Assessing_potential_hydrogen_cyanide_exposure_from_cyanide-contaminated_mine_tailing_management_practices_in_Thailand's_gold_mining A gold cyanidation ban refers to the legislation that
bans mining gold through the gold cyanidation technique. Germany, Czech Republic, Hungary, and Costa Rica have such bans, as well as the US states of Montana and Wisconsin and several Argentine provinces.
https://en.wikipedia.org/wiki/Gold_cyanidation_ban The following is a curious comment from a company admittedly using cyanide:
To date, mercury and
cyanide are the popular lixiviants used in the gold processing industry
. These chemicals are harmful to both the environment and humans and have been the major concern in gold mining
, Newlox Gold Ventures Corp, being the partner organization for the study, will have the opportunity to pilot the use of DMSO in gold leaching. (
BTW: The DMSO claim was never successfully proven.)
