The application of ore immobilization to the

2001-5-1  The interparticle friction observed in a slurry reactor can be eliminated by fixing the solid particles in space (immobilization). This idea was realized in the recently proposed concept of soil immobilization (Karamanev et al., 1996b).This concept is based on the entrapment of solid particles into the pores of a highly porous inert matrix with a wide pore size distribution, between several ...
