用尿素饱和水溶液，有机氯化物为活化剂，生成的尿素-正烷烃络合物成球状，易于过滤分离。
With water as urea solvent and an organic chlorine compound as activator, the adducts formed into small spheres which are easily filterable.
此阶段，环境从中碱性缓慢过渡到中酸性，金以胶体或氯化物络合物形式迁移。
During this stage, the pH value of the ore-fluids was slowly changed into medium-acidic properties. As a result, gold transported as colloid or the complex of chloride.
