No gold was lost, because his largest gold was around .5mm. The iCON method will improve your process by screening your feed to the proper size. This will reduce the volume of feed and increase the percentage of gold that you recover. iCON Gold Recovery uses a 2 step process; classification and concentration.

Run-of-mine ore is crushed and ground, free gold is recovered in a gravity circuit and flotation is used to recover a sulphide concentrate. This is then oxidised using autoclaves, producing feed for conventional carbon-in-pulp cyanide leaching to recover the contained gold. Low-grade stockpile and open pit ore are crushed using a gyratory crusher.

Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of small gold nuggets and flakes. Placer mining techniques since the mid to late 20th century have generally only been the practice of artisan miners.

Gold Recovery 101 Gold can be found in almost everything we see and touch; there are several important industrial uses for gold in electronics, dentistry and aerospace; however, almost 80% of gold ends up being used for jewellery. While jewellery is the end of the road for most mined gold, there are many ways it occurs in nature.

A sluice box recovers gold as a concentrate which has greater gold content. Recovery is a process of eliminating non-gold products from gold. Gravity methods rely on separation based on mass. The particles must have nearly equal size and different mass to be separated. There is a limit to the process of screening to smaller and smaller particle

Blasting, crushing, and grinding are necessary to liberate the gold for recovery. Hard rock gold deposits have three sub-classes: free-milling, sulfide-associated and refractory. Free-Milling Gold. Gold ore is considered free-milling when it is easily liberated by grinding and separated from the other minerals.

In generals, the concentration of gold includes three stages: roughing, cleaning and scavenging. The reason of concentration is to separate the raw material into two products, concentrate and tails. Ideally, in free gold recovery, all the gold will be in the concentrate and the other part will be in the tails.

At current gold prices this is worth about US$600. Both smelter treatment charges and oxidation or bio-leach costs are at least $200/t of concentrate and payables/recovery in the 90% range, so a minimum GSR for effective downstream processing is around 0.5. Clearly this is a function of gold price, but in the current gold price and cost
