Comparison of Methods for the Measurement of the Angle of Repose …
Abstract. The angle of repose—the maximum angle that allows a heap of soil to remain stable without failing—is an important property of soils and affects the safety and costs of projects such as slopes or retaining walls. But several methods have been proposed to measure it, which might produce confusion in practice and research. The …

33.4: Angle of Repose
For many granular materials a typical angle of repose will be between 25° and 40°. For smooth spherical particles all of the same size, a very simple model can be used to appreciate how the packing of spheres in three dimensions has consequences for the stability of slopes.

The depletion of nickel sulfide ores and their challenging extraction have prompted the exploitation of nickel oxide ores [2]. Limonitic and saprolitic are typical nickel oxide ores with nickel contents of around 0.5–1.8% wt and 1.8–3.0% wt, respectively. Hydrometallurgy is the predominant processing route for exploiting limonite ores [3], [4].

Angle of Repose
The angle of repose (θ) is calculated from the equation arc cos[D/(l 1 + l 2)]. The relationship between flow properties and angle of repose has been established. When the angle of repose is less than 25 degrees, the flow is said to be excellent; on the other hand, if the angle of repose is more than 40 degrees, the flow is considered to be poor.

How to Calculate the Angle of Repose
The angle of repose for dry sand has been calculated to be 35 degrees, whereas cement has an angle of repose of 20 degrees. Pour the dry sand into a pile on a level surface allowing it to build a pile from the top. This will result in a pile with a relatively circular base, making measurement easier.
