摘要： 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.
摘要翻译：一种沉积区域的恢复方法，使其适于植物生长，其包括颗粒状矿物材料，颗粒状矿物材料已经从所述材料的悬浮液中脱水，包括以下步骤：将颗粒状矿物材料的悬浮液作为流体转移至沉积区域，并且其中使悬浮液在沉积区域处静置并脱水以形成脱水颗粒矿物材料，其中处理区域的恢复是通过向颗粒悬浮液中加入脱水量的聚合物来实现的矿物材料，同时作为流体转移到沉积区域，其中所述聚合物是由一种或多种特性粘度为至少4dl / g或水溶性的一种或多种烯键式不饱和单体形成的合成水溶性聚合物聚合物，其是天然聚合物或半天然聚合物。
