Society has always needed mineral resources, both as commodities themselves, such as talc, and as sources of metals such as nickel. The extraction of minerals involves size reduction of mined rock (ore) and separation of minerals, together known as 'mineral processing'. Given Canada's abundant natural resources, mineral processing is practiced on a huge scale, billions of tons of ore annually, and thus process improvements can realize large benefits, economic and environmental. The importance to Canada is recognized in the series of industry-sponsored grants starting in 1991 of which this is the latest. There are seven companies supporting this grant directed at improvements in aspects of mineral processing: flotation, physical separations and environmental.

社会总是需要矿物资源，既作为商品本身，如滑石，也作为金属的来源，如镍。矿物的提取涉及开采岩石（矿石）的尺寸减小和矿物的分离，统称为“矿物加工”。鉴于加拿大丰富的自然资源，选矿规模巨大，每年数十亿吨矿石，因此工艺改进可以实现巨大的经济和环境效益。从1991年开始的一系列工业赞助赠款承认了对加拿大的重要性，这是最近的一次。有七家公司支持这项赠款，旨在改善矿物加工的各个方面：浮选，物理分离和环境。
