Mineral processing utilizes many toxic or hazardous reagents which have adverse health effects in the workplace and pollute the environment after disposal in tailing ponds. The progressive tightening of wastewater and health regulations portends a future where the industry, to preserve its social license, will be forced to replace the toxic reagents by the greener alternatives. To meet this need, it is important to develop greener renewable alternatives to the conventional surfactants (e.g. collectors and regulators in flotation).

矿物加工使用许多有毒或危险的试剂，这些试剂在工作场所对健康产生不利影响，并在尾矿池中处置后污染环境。废水和健康法规的逐步收紧预示着未来，该行业为了保持其社会许可证，将被迫用更环保的替代品取代有毒试剂。为了满足这一需求，开发更绿色的可再生替代品来替代传统的表面活性剂（例如浮选中的捕收剂和调节剂）是很重要的。
