Potential of lead/zinc slag for use in cemented mine backfill
On the other hand, there is evidence for the retardation of setting times and strength growth by the high zinc content in the slag. Zinc in the cement and in tailings used for the paste could limit the use of the lead/zinc slag and even iron blast furnace slag as cementing material in mine paste backfill.
