Process Control in metallurgical plants—From an Xstrata perspective

Abstract. Some history and modern practice of Process Control in metallurgical operations is reviewed. Clearly the early deliverables from the pioneer days in the 1950s through to the 1970s and early 1980s were under-appreciated. The discipline has since grown into a more visible, sophisticated and accepted practice as a result of …

Metallurgical Plant Sampling Techniques

Concentrator Slurry Sampling In milling operations sampling is essential to proper control. This can only be based on the results obtained through sampling the various materials throughout a plant. Sampling of the feed, concentrates, tailings and other products give data indicating the effectiveness of the entire operation. Often these …

Metallurgical Accounting Standards in Process Plants

Metallurgical accounting can be defined as the monitoring of the valuable metals from the time the ore is broken at the primary crusher until the time that we have the saleable products and residues. The overall purpose of metallurgical accounting is to provide management with up-to-date inform- ation that can be used to control mining and …

How Gold Is Mined | Gold Mining Process | World Gold …

The gold mining operation stage represents the productive life of a gold mine, during which ore is extracted and processed into gold. Processing gold involves transforming rock and ore into a metallic alloy of substantial purity – known as doré – typically containing between 60-90% gold. During its life, a number of factors – such as the ...

The same applies for gold mining complexes such as the Sibanye Stillwater Driefontein Mining Complex in South Africa where ore comes from multiple shafts (e.g. requires assays-based accounting at ore source/shaft), but processed in a central metallurgical facility (e.g. requires batch accounting or single point sampling of feed …

Principles of Screening and Sizing

Half size in feed – Higher % of half size increases capacity •. Oversize in feed – Lower % of oversize increases capacity •. Wet screening – Increases capacity •. Slotted openings – Increases capacity •. Finer wire diameter <. open area – Increases capacity & efficiency •. Reduce efficiency rate – Increase capacity •.
