C J Liang,J Y Li +1 more
TLDR
Gold leaching in iodine-iodide solution has been intensely researched in 1980s; while due to the high cost, it has not been applied in industry as discussed by the authors. But, as the drawbacks of other hydrometallurgi...Abstract:

Alternatives to cyanide in the gold mining industry: what prospects for the future?
Gavin Hilson,A.J. Monhemius +1 more
TL;DR: In this paper, a series of alternative lixiviant systems for the recovery of gold from ores and concentrates are reviewed, but none has yet made any significant inroad into the dominant position of cyanide as the reagent of choice at the vast majority of gold mines worldwide.
