野花从有毒土壤中吸收镍元素
菊科的一些植物(包括雏菊)属于一个不寻常的群体,被称为 "超积累者"。这些物种从根部吸收金属,并以极高的浓度将其储存在组织中,这种能力可能是作为一种抵御食草动物和病原体的防御机制进化而来的。在 750 种已知的超积累物种中,大多数都能在铜、钴、锂、镍和稀土元素含量有毒的田地里茁壮成长。这些植物将金属储存在叶片细胞的液泡中。为了提高植物采矿能力,GenoMines 增加了植物的高度和叶片的大小。GenoMines 团队在富含镍的田地里种植高积累植物,六个月后收获。然后,公司通过包括生物浸出在内的多种技术从生物质中回收金属,每年每公顷可提取 2.5 吨镍。这一过程不仅能获得镍,而且通过提取金属,植物还能修复土地。
