Anaconda Mining Inc is the industry partner in this application. They produce approximately 400,000 tonnes of RD annually as a waste byproduct from precious metal (gold) mining, and have unique volume of this material for potential commercial use. Preliminary investigations determined the chemical composition of the rock dust (RD) waste material is within acceptable limits for vegetable crop cultivation.The proposed study seek to evaluate the potential of RD generated as a waste product of precious metal mining as a suitable natural media amendment for forest reclamation and agriculture crop production. Furthermore, wood chip biomass is used successfully to scavenge ammonia following gold processing at the Industry partners operation. This work proposed to also evaluate the potential of the wood chip biomass as a useful source of nitrogen for crop growth under controlled environmental conditions. The first stage of this project will involve a comprehensive chemical analysis of the RD to determine contaminants and mineral nutrient composition for crop growth. In the second stage, we will use the RD chemical composition to formulate different combinations of soil or media mixes with RD to evaluate suitability for crop production under field and greenhouse conditions. In the third stage, we will seek to determine the potential of RD for boreal forest reclamation after resource mining. In the final stage, we proposed to develop a RD or wood chip biomass based media as a proof of concept for controlled environment crop production. The proposed study is a multidisciplinary applied research project that will be of mutual benefits to the academic and industry partners. Outputs generated from this study will contribute to better understanding of the quality of the RD waste material and nitrogen enriched wood chip biomass, suitability for field and greenhouse crop production/forest reclamation, mechanisms associated with RD role in crop biofortification, as well as HQP training opportunities for graduate students. The industry partner will use these results to generate commercial opportunities or use of this waste products as a new revenue stream for the company. Furthermore, the use of RD or wood chip biomass as a natural media amendment will provide opportunities for increase food production in NL and could be part of a long term strategy to mitigate current challenges with food security in the Province.

Anaconda Mining Inc是此应用程序的行业合作伙伴。它们每年生产约40万吨RD作为珍贵金属（黄金）开采的废物副产品，并具有该材料的独特量，以供潜在的商业用途。初步研究确定了岩石尘（RD）废料的化学组成在植物作物种植的可接受范围内。拟议的研究旨在评估作为珍贵金属挖掘的废物产生的RD的潜力，作为适当的自然媒体修正案，作为森林回收和农业生产的合适自然媒体修正案。此外，在行业合作伙伴的运营中，木芯片生物量成功地用于清除氨。这项工作建议还评估木芯片生物量作为在受控环境条件下农作物生长的有用来源。 该项目的第一阶段将涉及对RD进行全面的化学分析，以确定污染物和矿物营养成分的作物生长。在第二阶段，我们将使用RD化学成分与RD一起制定土壤或培养基混合物的不同组合，以评估在田间和温室条件下对作物生产的适用性。在第三阶段，我们将寻求确定RD在资源开采后对北方森林开垦的潜力。在最后阶段，我们建议开发基于RD或木芯片生物量的媒体，以作为受控环境作物生产的概念证明。 拟议的研究是一个多学科应用研究项目，对学术和行业伙伴会带来互惠互利。这项研究产生的产量将有助于更好地理解RD废料和富含氮的木芯片生物量的质量，适用于现场和温室作物生产/森林填料，与RD在作物生物体现中的作用相关的机制，以及研究生HQP培训机会。行业合作伙伴将使用这些结果来产生商业机会或将这些废物作为公司的新收入来源。此外，使用RD或Wood Chip Biomass作为自然媒体修正案将为增加NL的粮食生产提供机会，并且可能是缓解该省粮食安全当前挑战的长期战略的一部分。
