世界上大约一半的锂是从澳大利亚矿山地下开采的。Benchmark Mineral Intelligence 的会员经理罗伯特·科尔伯恩 (Robert Colbourn) 表示,此类矿山可能会造成环境破坏,包括污染和栖息地丧失,包括污染和栖息地丧失。Benchmark Mineral Intelligence 是一家报告包括锂在内的各种金属的价格和需求的机构。
Even if phytomining never becomes competitive with current lithium extraction methods, it could be used in concert with them to enhance their efficiency. Further, if land managers are planting a new forest in an area whose soil has a high amount of lithium, cabbage also could be planted there, gobbling up lithium for later use for as long as the tree canopy doesn’t steal its sun, Cleary said.
Anderson has used phytomining to clean up the last scraps of gold — and contaminant mercury — after other forms of gold mining. The research out of Ireland also posits that phytomining could be used to extract lithium from places less ideal for traditional mining, such as low-grade ore bodies and metalliferous soils.
