A series of laboratory cementing experiments on the total tailings from a gold mine in Shandong Province were conducted by use of ordinary cement and polyhydrate material as binding materials.
The results indicated that the polyhydrate binding material can produce higher binding strength under lower dosage compared with the ordinary cement, so it is applied to cement total gold tailings.
" We use urban construction waste, mine tailings and urban solid wastes as raw material.We sort them by category and we transform them into a special printing ink."
