Basically, the amalgamation process comprises the following stages, crushing and grinding the ore until get a K80 of approximately 35 mesh. Finer values work and the final particle size is dependent on the mineralogy. The next stage is to pass the ore in the form of a thin pulp over a mercury covered copper or silver coated plate.

the ore. Grinding (or milling) of ore takes place in a ball mill and is the most expensive and energy intensive part of the process. The finer the grind size required the more energy and time is taken up. Two grind sizes were tested here with ore initially milled to p80 passing 106 m and again to p80 passing .
characterization studies on these units provide information about the occurrence of gold in ore samples ( gold particle size distribution, amount of gold recoverable by gravity) but not about the effect of operating variables for fullscale units such as top size of particle, feed rate, fluidization flow rate and rotation speed.
Arrastra, simple mill for grinding and pulverizing (typically) gold or silver ore. Roller mill, an equipment for the grinding or pulverizing of grain and other raw materials using cylinders; Stamp mill, a specialized machine for reducing ore to powder for .
The ground ore is then floated to produce a gold rich copper concentrate for filtration and sale to overseas smelters. Flotation tailings are then leached for further gold recovery. The ore processing rate is approximately 35 million tonnes per annum. Typical head grade is approximately gram per tonne gold and per cent copper.
A feasibility study on the production of gold at a fictitious mine (Moapa mine) in Elko County, Nevada is to be performed. The mine is capable of producing 325,800 tons of highgrade ore per year for 8 years. The deposit contains ounces of gold per ton of highgrade ore and can be acquired at a cost of 10 per ton of ore (cost of mining ore

establish the gold liberation is grinding in different times followed by concentration • Increasing grinding time increasing liberation. Example The average gold grade of this tailing from Crixás, Brazil is around to 1 g/tonne. Gold liberation was studied as follows:: Sample Grinding Fire Assay Batch tail. conc. no grinding
A total of 1700 kg of ore was processed through a continuous circuit which included grinding, gravity concentration and flotation to recover the gold and copper values in the ore. The following table summarizes the metallurgical balance. The gold feed grade is backcalculated from the products to be g/t or opMT. Gravity Concentrate
In a typical pyrytic gold ore, the gold is encapsulated within an iron sulfide crystal structure. Highly oxidized ores generally do not respond well to flotation. Advantages of the flotation process are that gold values are generally liberated at a fairly coarse particle size (28 mesh) which means that ore grinding costs are minimized.

past fifteen years, there has been a new gold rush with several persons becoming smallscale miners to escape complete social marginalization. Coupled with this, is the exhaustion of accessible placer ore deposits in Brazilian Amazon1,2,3,4, which are pushing garimpeiros (Brazilian gold miners) to invade neighboring countries.
