Mine tailings (MT) have been used in previous studies as substitute construction material to recycle waste products, especially in hollow blocks and bricks production and as masonry mortar. This study investigated the use of Philex copper-gold mine tailings (PCGMT) in roller compacted concrete (RCC) production, a mining waste material consisting of finely grinded siliceous particles was
14 行· A tailings dam is typically an earth-fill embankment dam used to store byproducts of mining
Open-pit and underground bulk mining by Philex in Tuba and Lepanto in Mankayan generate ore and tailings at a rate of up to 2,500 metric tons per mine per day. Toxic mine tailings are usually
The current underground mine design and plan is mostly based on the 2014 Didipio Technical Report, with a small modification to the mining method. On the Eastern side of the mine, the mining method has been changed from a combination of double-lift top-down and double-lift bottom-up longhole stoping to a strictly double-lift top- down approach.
