Congrats to you and your Midas touch! I am not a gold waster as I know it is a limited resource. I do purchase the gold cars from time to time but never paint or vinyl a car, skip levels, service etc.
Native gold and electrum are naturally-occurring alloys containing gold and silver and a little copper. They are the most common and important forms of gold in ores. Their recovery by gravity concentration, cyanidation, or flotation from ores, typically containing 0.1–20 g/t Au is of great commercial importance.

Leaching in the grinding circuit is currently practiced in plants that process gold ores with low content of cyanide consuming minerals. The high gold recovery observed in the grinding–classification section of the plant is commonly explained by the inherent high initial dissolution rate of gold observed in gold ore cyanidation, or by the intense agitation prevailing in grinding mills.

It was postulated that gold smearing can lead to metallurgical losses in flotation circuits. A gravity circuit could then increase overall gold recovery.The Knelson concentrator was used to study the behavior of gold in the Hemlo mill grinding circuit.
A Knowledge of the amount of time the material spends in a continuous mill in a closed-grinding-circuit is essential for circuit performance analysis and scale-up design. A convenient method for acquiring this information involves the use of tracers in residence-time-distribution (RTD) experiments.
