I guess when you see something like this you start wondering if you should just toss the classifier out of your sluice box. Soooooo how heavy is this shiny rock?

That's a bigun.  As to not classifying - you MUST classify - go ahead, run your sluice without classifying and you'll quickly understand - your sluice is more than just ' efficient' if you classify - classification is what allows it to work.

So, what to do? Take a quick look through the material that doesn't make it through your classifier. Depending on how you're classifying, you might just stir through your top-of-bucket screen before dumping, or you dump your material on your waste pile and stir/spread it around a bit as you eyeball it. There are wash systems that provide several classification/separation ranges where there is a significant size range of the material you want to save.  In general, best practiced is to classify, classify, classify into fairly tight size range and adjust your sluice for best capture of the heavies in that fraction.

Well classified material will run pretty fast with little loss. Poorly classified material will run much slower and loose more of your heavies. If running some size range through the sluice is not worth it for the little gold contained there-in, it definitely is not worth leaving that material in the next smaller/larger size fraction to run it through your recovery system.

In 1937 Alice Shea found this nugget wedged in a boulder while walking along Turnagain Creek to her husbandís claim in northern British Columbia. It is the largest existing gold nugget found in the province, weighing 1642 grams or 52 troy ounces. BCís Department of Mines bought the nugget for $1500.
