DOI: 10.1007/s11356-017-0731-6
Abstract: Waste rocks from gold mining in northeastern Thailand are classified as sandstone, siltstone, gossan, skarn, skarn-sulfide, massive sulfide, diorite, and limestone/marble. Among these rocks, skarn-sulfide and massive sulfide rocks have the potential to generate acid… read more here.

DOI: 10.1016/j.jclepro.2021.126160
Abstract: Abstract Waste rocks were obtained during the mining, and were identified as a solid waste. The waste rocks were mostly stockpiled due to lack of economic value, resulting in a large occupation of land and… read more here.

DOI: 10.3390/min8120552
Abstract: Crushed waste rock can be used as backfill in goafs to allow re-use of otherwise solid waste and to control surface subsidence. If a certain lateral stress is applied to crushed waste rocks beforehand, they… read more here.
