  • Gold extraction Wikipedia

    Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of small gold nuggets and flakes. Placer mining techniques since the mid to late 20th century have generally only been the practice of artisan miners. Hydraulic mining was used widely in the Californian gold rush, and involved

    Thiourea does have potential for extracting gold and silver from refractory ores and concentrates that have sufficient value to justify the use of thiourea as a reagent. As illustrated by the leaching results for the bulk concentrate reported in this article, thiourea yields substantially higher levels of gold and silver extraction than does cyanide. Dissolution is generally much faster in

  • The dissolution of gold in acidic solutions of thiourea

    01/02/1976· Iron(III) as the oxidant caused the most rapid initial rate of dissolution of gold, but this rate soon decreased because of the reaction between iron(III) and thiourea; this resulted in the con- sumption of an excessive amount of thiourea which made the use of iron(III) as the oxi- dant unattractive in any ore leaching system based upon the use of thiourea as leaching agent. The results

    Thiourea had a former use in the treatment of excessive thyroid gland activity. The doses of thiourea recommended vary considerably. Originally, a dose of 2-3 g daily was used, especially as an initial dose. This was later reduced because of the associated side-effects. The side-effects of thiourea have been described from observations of the former therapeutic use of thiourea in the 1940s as
