Considering versatile utilization of water in mining activities, huge amount of contaminated effluent is currently produced. In gold mine compagnies, the use of Ammonia Nitrate Fuel Oil (ANFO) for detonation and cyanide for precious metal recovery is generally leading to metal cations and oxyanions dissolution resulting in a highly contaminated effluent containing thiocyanate (SCN-), cyanate (OCN-), ammonia (NH4+), heavy metals and metalloids. Through this project, the Centre Technologique des Résidus Industriels (CTRI) will work with Bishop Water Technologies Inc. to assess a new technology named ''BiocordTM'' in order to eliminate N-based compounds from mining effluents which has proven to have negative impacts on the ecosystem. The data of this ongoing research project will provide Bishop Water with insight into potential technology that will help industry efforts to effectively treat N-based compounds (NBCs) in mining industry while respecting stringent regulations.

考虑到采矿活动中水的多种利用，目前会产生大量受污染的废水。在金矿公司中，使用硝酸铵燃料油 (ANFO) 进行爆轰，使用氰化物回收贵金属，通常会导致金属阳离子和氧阴离子溶解，从而产生含有硫氰酸盐 (SCN-)、氰酸盐 (OCN-)、氨 (NH4+)、重金属和类金属的高度污染的废水。通过该项目，残留工业技术中心 (CTRI) 将与 Bishop Water Technologies Inc. 合作，评估一项名为“BiocordTM”的新技术，以消除采矿废水中的氮基化合物，该化合物已被证明对生态系统有负面影响。这个正在进行的研究项目的数据将为 Bishop Water 提供对潜在技术的深入了解，这些技术将有助于行业努力有效地处理采矿业中的氮基化合物 (NBC)，同时遵守严格的法规。
