The standard method for producing gold in large mines is cyanidation (cyanide-in-leach, cyanide-in-column, or heap leaching are some applications). As the mining industry has faced growing opposition to the use of cyanide in gold production, it has developed an alternative, thiosulfate leaching. In this process thiosulfate replaces cyanide as the chemical which binds and extracts gold from the ore in the leaching tanks. Thiosulfate leaching however suffers from some drawbacks including difficulty recovering gold from thiosulfate leaching solutions. We have developed an alternative adsorbent for thiosulfate leaching. Our initial results encourage us to consider commercial applications and identify market opportunities. Here we propose to perform a market assessment.

大型矿山生产黄金的标准方法是氰化（氰化浸出、氰化物柱浸或堆浸是一些应用）。由于采矿业在黄金生产中使用氰化物面临越来越多的反对，因此开发了一种替代方案——硫代硫酸盐浸出。在此过程中，硫代硫酸盐取代氰化物作为化学物质，在浸出罐中从矿石中结合并提取金。然而，硫代硫酸盐浸出存在一些缺点，包括难以从硫代硫酸盐浸出溶液中回收金。我们开发了一种用于硫代硫酸盐浸出的替代吸附剂。我们的初步结果鼓励我们考虑商业应用并确定市场机会。在这里我们建议进行市场评估。
