Achieving hydrophobic surfaces on mineral particles is an active research topic in mineral processing. The conventional technique for achieving good hydrophobicity is to mix mineral particles in solutions of organic salts ...
Comparison of flash flotation and gravity separation performance in a greenfield gold project
Erkan, Emre; EKMEKÇİ, ZAFİR; Altun, Naci Emre (2022-01-01)
Recovery of gold and gold-containing sulfide mineral particles requires multiple-stage recovery processes starting from the grinding circuits to avoid over-grinding of the liberated gold particles. Due to high density, the...
DETERMINATION OF AGGLOMERATION CHARACTERISTICS OF OLTU-STONE (JET STONE) WASTES
Bawani, Muhammad Raheel; Arol, Ali İhsan; Tozsin, Gülşen; Department of Mining Engineering (2021-12-17)
Oltu-stone (Jet Stone), also known as black amber, is a fossilized, organic, and natural material formed by the transformation of certain trees under high pressure. It is called Oltu-stone because its occurrences are prima...
STABILITY AND FAILURE ANALYSIS OF EXCAVATIONS USED FOR UNDERGROUND MINING OF BATI RAMAN OIL FIELD
Emci, Mehmet Emircan; Öztürk, Hasan; Department of Mining Engineering (2021-11-8)
Batı Raman holds the Turkey's proven largest oil reserve (1.85 billion barrels). The reserve is located at an average depth of 1450 m within a fractured limestone. This heavy oil has a 12° API gravity and a viscosity of 20...
