Methodology for determination of rock durability with special attention to waste rock from metallic mineral deposits

Chemical‐mechanical weathering of waste rocks from metallic mineral deposits leads to reduction of their strength and deformability. This is of great importance if there is intention to use these rocks as construction material for large structures such as rock fill dams, high embankments or levees....

Description
Summary:Chemical‐mechanical weathering of waste rocks from metallic mineral deposits leads to reduction of their strength and deformability. This is of great importance if there is intention to use these rocks as construction material for large structures such as rock fill dams, high embankments or levees. Thus, determination of rock durability is essential in avoiding disintegration of the structures with time. The paper presents the outcomes from procedure with modification of the slake durability test that was applied to several types of waste rocks from a sulfide copper deposit. In addition, an overview is presented of time‐dependant weathering correlations for soft rocks, and possibility to develop similar correlations for hard rock resistance properties based on this research. Suggested methodology for durability testing of hard rocks is also presented. It is believed that application of such methodology will provide more realistic information about the long‐term weathering behavior of the waste rock construction materials.
