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.

在大型金矿中生产黄金的标准方法是氰化法（氰化浸出，氰化柱或堆浸是一些应用）。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，它开发了一种替代方法，硫代硫酸盐浸出。在这个过程中，硫代硫酸盐取代氰化物作为化学品，在浸出槽中从矿石中结合和提取黄金。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。我们已经开发了一种替代吸附剂硫代硫酸盐浸出。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。
