Gold Processing | Equipment, Process Flow, Cases
Gold flotation. Flotation process is widely used for lode gold processing. In most cases, the flotation method has a good effect in sulfide-containing gold ore with high floatability. In addition, the flotation process is also used for polymetallic gold-bearing ores such as gold-copper, gold-lead, gold-copper-lead-zinc-sulfur ore.

On the other hand, they have been found poorly suited to the hard, rocky ground encountered in many gold placers. The successful use of rotary bucket drills to sample dry placers has been described in articles by Draper and by Prommel. Prommel describes a sampling project in which 1,239 test holes 28 inches in diameter were drilled in 147 days.

Rock Crushers
Once primarily used by landscapers and contractors to crush rock for demolition, gold miners are now using them to both test material in the field, and recover gold back at home. In most cases, you can take your rock crusher straight from the shipping container and use it in less than half an hour.

Blasting is also used to remove pockets of unwanted material that are preventing mining machines and personnel to get to the seam containing the materials of interest. Unmanned drill rigs will drill holes at pre-determined depths and positions on a blast face to ensure that a particular size fraction is achieved and that little of the overburden is liberated with the blasting to reduce

Open Pit Mining Techniques|Surface Mines|Rock or Mineral Extraction
Open Pit Mining. Open-pit mining, also known as opencast mining, open-cut mining, and strip mining, means a process of digging out rock or minerals from the earth by their elimination from an open pit or borrow. The word is used to distinguish this type of mining from extractive methods that need tunneling into the earth.

Hard Rock Mining Gold and Silver Ore and processing it
There are a number of different haulage methods for transporting rock through a mine to the portal. The old timers commonly used rail and mining cars to move gold or silver ore and waste rock, and this method is still used in some smaller mines. Most modern mines however, use rubber tired diesel powered equipment to haul ore underground.

Extracting Gold | HowStuffWorks
To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel. The gravel-like material then enters rotating drums filled with steel balls.

Hard Rock Mining vs. Placer Gold Mining
Gold is found in two ways; as hard rock sources within ore, and as placer deposits where the gold has separated from its host material. Most prospectors today prefer placer mining because they can use simple tools like gold pans and sluice boxes, but don''t overlook hard rock sources either!
