How to Value a Gold Deposit

Real Value of Gold in the Ground

How do you measure the value of gold a gold deposit still in the ground in terms of a company that is mining or in production exploration stage? The starting premise is how we value advanced explorers and developers to target companies that are undervalued with respect to their peers and evaluate how viable they’re […]

Lime Slaking Equipment

Lime slaking systems

A lime slaking and addition system can consists of two systems to control the pH in the rougher and cleaner flotation circuits. A pebble lime silo will dose dry lime to the SAG mill feed belt; a hydrated lime make down system will provide slurry lime to multiple addition points in the flotation circuit. Other lime […]

Polaris was such a nice workplace. Maybe my memories of it are skewed a bit be the fact it was my very first really mining job, but in any case, I only remember a very nice spirit up there. I also remember the Chili Peppers and the Polar Beach Party. https://www.lostmines.net/polaris-mine.html

SABC Grinding Circuit Operation & Optimization

Grinding Cuircuit Flowsheet SAG ball mill and pebble crusher SABC configurations

When operating a grinding circuit (at Granny Smith) under a wide range of conditions: campaigning very competent underground ore followed by soft oxide, primary versus secondary crushed feed and finally single-stage SAG and conventional SAG, ball mill and pebble crusher (SABC) configurations.  Economics changed and a review of the circuit performance including modelling and simulation resulted in the […]

Effect of Flotation Density on Grade and Recovery

effect of flotation cell volume

In an effort to test the Effect of Flotation Cell Size in Laboratory, I ended up with a test for the effect of flotation density on grade and recovery. Therefore,  I here present is a Laboratory experiment that counters the reality of a full scale industrial flotation plant. By “counters the reality” I mean, larger commercial […]

Processing Gold by Cyanidation Leaching

Ways to Process Gold

Processing Heap Leachable Gold Ore by Cyanidation Oxide ore (low grades) will be unloaded on the heap leach PAD. Lime must be added during the discharge in order to control pH.  Harvesting must be performed after the ore discharge is completed in order to avoid compaction caused by the trucks during the leach cell construction. After […]

Falcon Gold Tracker -MD20 Reviews
