The goals of this project are to develop (1) a practical methodology to categorize different gold ores based on the mineralogy, and (2) an effective method to determine the optimum method for gold recovery from gold ores and concentrates. The project will focus on treatment of difficult-to-treat ores. Most of the ores in this group have sulphide phases in their structure. These ores may also contain penalty elements which lower the value of the concentrate. Arsenic, a toxin, is an example of a penalty element. If not treated with proper processes, the penalty elements may be released into the environment and contaminate the air and soil in the vicinity of the mine sites. Thus, the development of processes that are optimized to the feeds from each mine is crucial to ensure the maximum yield with the minimum environmental impact. As a result of this project, XPS Consulting & Testwork Services will be able to provide their clients a more detailed description of the gold ore and outcome from processing. In addition, XPS would also be able to recommend the most economical, sustainable, and environmentally responsible process for gold extraction to their Canadian and international clients.

该项目的目标是开发（1）一种实用的方法，根据矿物学对不同的金矿石进行分类，以及（2）一种有效的方法，以确定从金矿石和精矿中回收金的最佳方法。该项目将侧重于难处理矿石的处理。这类矿石中的大多数在其结构中具有硫化物相。这些矿石也可能含有惩罚元素，降低精矿的价值。砷是一种毒素，是惩罚元素的一个例子。如果不经过适当的处理，有害元素可能会释放到环境中，污染矿区附近的空气和土壤。因此，开发针对每个矿山的进料进行优化的工艺对于确保最大产量和最小环境影响至关重要。 通过该项目，XPS咨询和测试服务公司将能够为客户提供更详细的金矿石和加工成果描述。此外，XPS还能够向加拿大和国际客户推荐最经济、可持续和对环境负责的黄金提取工艺。
