摘要
The method aims to cover residual salt tips created during salt processing, for the purpose of re-cultivation and grassing-over. Bindeable residual materials and further fillers are mixed with water or a watery salt solution, to form a green granulate of low cohesion. The green granulate is applied to the tip from above, pref. in free fall. The bindeable component and filler materials are mixed at a ratio of 20:80 to 30:70 in a mixer, and 10-30% of water/solution is added, so that a rolling crumbly granulate is achieved. Cohesion of the material on the tip increases steadily, resulting in an even thin layer. The materials are pref. power station ashes and e.g. water-insoluble clay-like aluminum oxide, created during processing of aluminum slag.
