Stereological Corrections
In reflected light mineralogical studies involving opaque minerals, it is possible to section a composite particle so that the particle appears to be liberated. Clearly, a binary particle may be sectioned to appear liberated but a liberated particle cannot be sectioned to appear locked. The probability of this former occurrence depends upon the relative amounts […]

Titration of Cyanide Solutions Containing Dissolved Copper

When silver nitrate is added to sodium cuprocyanide of the composition Na2Cu(CN)3, an appreciable amount must be added before a precipitate comes down. The reactions are believed to be as follows: 2 Na2Cu(CN)3 + AgNO2 = 2 NaCu(CN)2 + NaAg(CN)2 + NaNO3 On further addition of silver nitrate, a precipitate of CuCN begins to come […]
Effect of Flotation Density on Grade and Recovery

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 […]

Compare X-Ray to Laboratory Analysis

If you run a standard assay laboratory analysis you might wonder if an XRF Spectrometer could provide enough precision or accuracy on some of your less important samples (production geology for example). What about an XRF vs AA comparison? What is an XRF’s Measurement Reliability & how does an X-Ray/XRF compare to a laboratory? I once ran […]
