12 uses of mine waste rock and tailings
(6) It is used to produce all kinds of bricks. At present, coal gangue brick has become one of the main wall building materials to replace clay brick. It can not only burn gangue red brick, but also burn hollow brick. In fact, many shale waste rocks are also suitable for brick making, but the energy consumption is higher than gangue brick.

Mining and Beneficiation Waste Production and Utilization
The use of mine tailings in the production of bricks and blocks was investigated as early as 1979 by Collins and Miller as part of an intensive research into waste utilization in the United States. Copper, lead, zinc and iron ore tailings from various U.S. sources were evaluated in the production of cemented blocks.

All You Need To Know About Brick Recycling | Go Smart Bricks
Bricks are made of mining shale and other raw materials that are costly as well as bad for the environment. If the waste materials can be used again, it will not only cut down on mining but also save on extra costing, which is a win-win situation for both environment and people.

Recycling, Reuse and Rehabilitation of Mine Wastes
Reuse and Recycling of Waste Rocks Rehabilitation of mine sites and waste repositories commonly makes use of benign waste rocks for landscaping as well as capping and revegetation of waste repositories (Table 1). Waste rocks are also exploited as backfill in open voids, reducing waste piles and leaving fewer mine work-ings.

Sustainable use of mine waste and tailings with suitable
Almost every coal as well as metal mining produces waste rock. The quantity of waste produced (shale and sandstone) in coal mines is in-terms of millions of cu.m per year. Sandstone is a highly porous rock and the strength is medium, so it may not be suitable for pavements. On the other hand, iron ore waste will have better strength, which

SUSTAINABLE CLAY BRICK PRODUCTION – A CASE STUDY
At Gasser mining of raw materials has been greatly reduced by substitut-ing quarried materials with waste materials. Nevertheless quarry operations require great attention in the fu-ture in order to further minimize the impact. A measure to reduce the impact of the mining operations is to rebuilt mining areas at the end of their useful life.
