以改进的植物生长修复处理矿物浆料

Treatment of mineral slurries with improved plant growth rehabilitation

Abstract

修复沉积区域以使其适用于植物生长的方法,所述沉积区域包括颗粒状矿物材料,该颗粒状矿物材料已经从所述材料的悬浮液中脱水,该方法包括以流体的形式将颗粒状矿物材料的悬浮液输送到沉积区域的步骤,并且其中允许悬浮液在沉积区域静置并脱水而形成脱水的颗粒状矿物材料,其中,当颗粒状矿物材料的悬浮液以流体的形式被输送到沉积区域时,通过将脱水数量的聚合物添加到所述悬浮液中来实现处置区域的修复,其中所述聚合物是由一种或多种烯属不饱和单体形成的具有至少4dl/g的特性粘数的合成的水溶性聚合物或者为天然聚合物或半天然聚合物的水溶性聚合物。
A method of rehabilitation of a deposition area to render it suitable for plant growth comprising a particulate mineral material, which particulate mineral material has been dewatered from a suspension of said material, comprising the steps of transferring the suspension of particulate mineral material as a fluid to the deposition area, and in which the suspension is allowed to stand and dewater at the deposition area to form a dewatered particulate mineral material, wherein the rehabilitation of the disposal area is achieved by adding a dewatering amount of a polymer to the suspension of the particulate mineral material while it is being transferred as a fluid to the deposition area, wherein the polymer is either a synthetic water-soluble polymer formed from one or more ethylenically unsaturated monomers having an intrinsic viscosity of at least 4 dl/g or a water-soluble polymer that is a natural polymer or semi natural polymer.
