Market assessment for a new gold adsorbent for use in thiosulfate leaching

大型矿山生产黄金的标准方法是氰化(氰化浸出、柱中氰化或堆浸)。随着采矿业越来越多地反对在黄金生产中使用氰化物，它开发了一种替代方法，即硫代硫酸盐浸出。在这个过程中，硫代硫酸盐取代了氰化物，成为从浸出槽中的矿石中结合和提取金的化学物质。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液中回收金。我们开发了一种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寻找市场机会。在这里，我们建议进行一次市场评估。

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.
