Analyzing Complex Ores with ZEISS

Discover the advantages and possibilities

Supplying the mineral resources to satisfy the increasing societal demands for infrastructure, advanced technology, and cleaner energy production requires detailed knowledge of the ore body, and of the mineralogy that influences behavior during the beneficiation process and beyond mine closure. Find out how ZEISS Microscopy provides you with actionable information to address challenges across the entire mining value chain.

Automated Quantitative Mineralogy of Sub-Micron Gold

Detection, Analysis, Description, Quantification and Refractoriness

Gold deposits can display mineralogical and textural variability that serve to add complexity to the recovery process. The intricate nature of an ore, regardless of whether the gold is refractory or free milling, can be explained in terms of the variability of the Au-bearing phases, the granulometry and the ore’s modal mineralogy (Goodall and Scales. 2007). All three characteristics interact to affect gold recovery by a variety of mechanisms. Modern microscopy techniques can afford exacting quantification of gold presence as well as a description of its environment. Therefore, it is a logical deduction that continuous monitoring of the texture and mineralogy of the ore can lead to an understanding of the ore’s behavior and discernment ofthe intricacies of how mineralogy affects metallurgical recovery.

Visualization of gold and uranium ore-formation

Read more in the whitepaper

The Witwatersrand basin in South Africa represents the largest known gold resource on Earth. Despite decades of intensive research, the genesis of the gold-uranium ore is a matter of considerable debate. An analytical approach using the novel Atlas 5 workflow visualizes the process of gold and uranium ore-formation, from micro-to-nanoscale in both 2D and 3D, and uncovers the key-role of hydrocarbons in the metallogenesis
