چکیده
Shear zone hosted lode gold type deposits at the El Bagre in northeastern of Antioquia department Colombia, are only evidence Permian mineralization to date Colombia Andes. Orebodies structurally controlled and considered as product ore-forming fluids derived from least two episodes fluid flow between shear zones, thus different could lead orebodies ore shoots plunge directions. The La Ye tend strike NNW-NS SW, Mangos (as a whole) NS-NNE NE Cordero NE. ellipses determined by variogram modelling for these orebodies, reveal anisotropy therefore orientation ore-shoots. long axes trend SSE. These high grades distributions related sinistral shearing NNW-SSE faulting during D3 deformation event. This study exemplifies simple effective tool exploration strategies regarding ore-shoots ore-controlling structures relationships

DETERMINATION OF THE OPTIMUM CONDITIONS FOR RECOVERY OF GOLD FROM ZARSHURAN REFRACTORY GOLD SULFIDE ORE
The orthogonal array design has been used to determine the optimum conditions for gold recovery from Zarshuran refractory gold sulfide ore (Iran) by direct cyanidation and roasting-cyanidation. The Taguchi method was used as the experimental design to determine the optimum conditions of dissolution behavior of gold with cyanidation and roasting-cyanidation from Zarshuran refractory gold ore . T...
متن کاملNickel ore grinding energy determination
This study describes the application of an empirical method to estimate the energy consumption in laboratory of the primary grinding of nickel ore with a specific mineralogical texture. This method developed by Donda was previously used in iron ore from the Iron Quadrangle (Minas Gerais, Brasil) with the same purpose. Through the grinding test, performed under standard conditions and based on t...
متن کاملOre-type graph packing problems
We say that n-vertex graphs G1, G2, . . . , Gk pack if there exist injective mappings of their vertex sets onto [n] = {1, . . . , n} such that the images of the edge sets do not intersect. The notion of packing allows one to make some problems on graphs more natural or more general. Clearly, two n-vertex graphs G1 and G2 pack if and only if G1 is a subgraph of the complement G2 of G2. In terms ...
متن کاملDouble Ore Extensions versus Iterated Ore Extensions
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...

A highly sensitive, selective and rapid method for the determination μg L(-1) level of Au(III) based on the rapid reaction of Au(III) with 2,3-dichloro-6-(3-carboxy-2-hydroxy-1-naphthylazo)quinoxaline (DCHNAQ) and the solid phase extraction of the colored complex with a reversed phase polymer-based C18 cartridge have been developed. The DCHNAQ reacted with Au(III) to form a violet complex of a ...
