A number of considerations should be taken into account in design stage to avoid the foregoing malfunctions of vertical silos containing ore concentrate. One of the silo problems is obstruction at the outlet which blocks the material flow. There are procedures, depending on the material properties and silo dimensions, to solve this problem. A common way is impacting the silo wall by manual hamm...

Vertical silos are large cylinders used for material storage in agriculture and mineral industries. One of the silo problems is its obstruction due to dome and dense packing. Depend on the material properties and silo dimensions several techniques are used to solve this problem. In the present work, possibility of obstruction solution of a laboratory silo by ball impact is investigated. Test ma...

Abstract: point of view. In this study, a shaking-table was used for concentrating a manganese ore sample from the Ghasem Abadarea in Kerman, Iran. Experiments were designed by using LThe influence of each variable and their interactions on the operation of the device was studied. The variables underinvestigation were: table slope, table frequency, water flowrate, feed rate, and particle size. ...

Motivated by the construction of new examples of Artin-Schelter regular algebras of global dimension four, J.J.Zhang and J.Zhang (2008) introduced an algebra extension AP [y1, y2;σ, δ, τ ] of A, which they called a double Ore extension. This construction seems to be similar to that of a two-step iterated Ore extension over A. The aim of this paper is to describe those double Ore extensions whic...

According to the publication by US Minerals Survey in 1999, the total reserve of manganese ore in the world is 0.66 billion tons. See Table 1.

Obtaining detailed and precise information from a classified refractory gold ore has been long-standing challenge in mineral processing process mineralogy. Although the concept of diagnostic leaching extensively addressed literature, very little is available linking this approach with current advanced characterization techniques such as automated The present research study aims to characterize ...
