1. Introduction. In its simplest definition, gravity concentration is a class of methods which take advantage of the density differences among mineral particles [1], [2], [3].As a result, particles of which densities are different from each other have their own relative movement against the forces of the gravity depending on the factors such as …

3. Using gravity separation method, we can discard the block rock and coarse tailings, and recover the weak magnetic mineral with coarser grain size; 4. Gravity separation method can be used as combined method with other mineral processing methods to recover weak magnetic minerals with fine grain size. 5.
We present here a singular spectrum analysis (SSA)-based low pass filtering algorithm for regional and residual gravity anomaly separation. The data adaptive decomposition in SSA frequency filtering algorithm facilitates reduction of the artefacts in the filtering of the non-linear and non-stationary gravity data. Initially, the method was …
