Sand modification with a saponite clay suspension as a waste of the diamond mining industry

The results of the laboratory water permeability tests a sand modified by saponite clay fraction from diamond mining industry waste are presented. filtration suspension through landfill ground bed as method additive enrichment is approved. experimental apparatus consisted triaxial test chambers and semi-automatic devices for supplying. excluded sidewall leakage in samples provided required values vertical horizontal stresses when measuring permeability. an alluvial fine mixed with 3 5 % chalk dolomite were investigated. After preliminary saturation rate distilled flow determined at four hydraulic gradient. Then containing up to 0.58-0.63 particles was conducted. that, pore disks top washed circulating flow. At last step experiments velocity measured again indicated that modification clogging pores possible if comprises additives causing aggregation particles. conductivity decreased 15-31 times, - 15-39 times different relative compaction. effect addition not significant, maximum 14.3 times. To achieve depth clogging, it recommended filtrate loose gradient provides more than 3.5 m/day, after layer should be compacted.
