MEJORAS EN METODO PARA SOLIDIFICAR SUSPENSIONES DE LODOS DE DESECHO |
摘要 |
<p>Solidification of colloidal argillaceous matter in essentially non-settling, aqueous slime media into a solid stable matrix is accomplished by mixing such slime with a hydratable calcium sulfate and hydrating to form an interlocking strength bearing matrix. The method is particularly useful for coalescing phosphatic clay slimes with hydratable calcium sulfate prepared from the co-produced waste phosphogypsum.</p> |
