1. The mixtures of 2-P-HEMA with ethanol or DMSO were precipitated to formed flocci form solid after injection into water.
2-P-HEMA的乙醇或DMSO溶液注入水中呈絮状固化。
2. There are two challenges in the heap leaching technology, one is the leaching rate and the other is the flocci in the extraction process.
堆浸技术中有两大难题，一是浸出率，二是萃取中的絮状物。
3. Discussion on the Heap Leaching Mechanism of Low grade Ores and the Cause of Flocci Formation
低品位矿石堆浸机理及絮状物成因的探讨
