Selection on the Process for Removing and Recovering Antimony from Antimonial Refractory Gold Ores

2017
It is well known that the gold ores containing a high content of arsenic and antimony are very refractory. In this paper, the adverse effect of antimony on the extraction of gold by pretreatment-cyanide leaching was discussed in detail. Moreover, these processes of removing and recovering antimony from alkaline sodium sulfide or hydrochloric acid ...

The Bacterial Leaching of Antimony- and Bismuth- Bearing Ores and the Utilization of Sewage Waters

1980
Microorganisms are widely used in many technical processes. One of the main purposes of this paper is to report some of the changes which occur in mineral ores under the influence of different types of bacteria. Studies on these changes have made it possible to develop methods for the extraction of manganese, uranium, and especially copper, from some ...

PRINCIPAL TYPES OF STRUCTURES IN ORE FIELDS AND ORE DEPOSITS OF THE SOUTH FERGANA MERCURY-ANTIMONY BELT

International Geology Review, 1964
The South Fergana Mercury-Antimony Belt extends parallel to Variscan structures along the north slopes of the Alay, Turkestan, and Nuratin mountains. Three principal types of ore deposits are recognized: 1) high-temperature complex-composition vein deposits, 2) tabular mercury or mercury-antimony deposits in jasperiod-hornfels breccia at limestone ...
