This paper proposes an architecture for integrating geology data, surveying data, minerals original data and establishing visualization application systems in mine. In this architecture, geology data, surveying data and minerals data are classified and integrated in the original database. The original database and corresponding database management system (DBMS) can provide a common and standard...

Imaging spectrometer data (also known as 'hyperspectral imagery' or HSI) are well established for detailed mineral mapping from airborne and satellite systems. Overhead data, however, have substantial additional potential when used together with ground-based measurements. An imaging spectrometer system was used to acquire airborne measurements and to image in-place outcrops (mine walls) and box...

The oxidation of iron sulfides in mine wastes is the main cause of acidic, sulfate, and trace element-rich acid mine drainage (AMD). However, the suite of reactions that transform iron from one species to another is quite complex. A reasonable strategy for controlling AMD production is to identify and further slow the slowest, rate-determining step (RDS) in the overall process. This paper provi...

Since the first scientific observations on mining environments over 400 years ago, we have gained some phenomenal knowledge on mine, land and waterways degradation and related environmental protection issues. Yet today, we continue to be faced with numerous challenges, including the recurring failure of mine waste repositories, the unconstrained production of acid rock drainage and the widespre...

Geometallurgical mapping is a new team-based approach that documents variability within an orebody and quantifies the impact of geology (host rocks, alteration and structure) and mineralogy on grinding, metallurgical response and metal recovery processes. The quantitative, spatially constrained database that results can be readily integrated into 3-D block models and mine planning activities. T...
