We recommend a maximum feed pressure of 125kPa for fine feed, and a maximum of 100kPa for coarse feed, to prevent excessive wear. But for fine particles or dilute feeds, the maximum pressure can be as high as 300kPa for the smaller cyclones – 400mmØ and less. Recommended maximum feed pressures are –. Cyclone Diameter.
Suitable for processing natural gold embedded in coarse particle size, stored in pyrite and other sulfide ores. Different from single flotation is to add mercury plate for gold recovery after grinding, the recovery rate can reach 30-45%. After mercury amalgamation, the slurry is flotation through the overflow of the classifier.
Gold ore drops as raw gold if mined by an iron pickaxe or higher. If mined by any other tool, it drops nothing. Mining with a Silk Touch pickaxe drops itself. It is affected by Fortune enchantment, dropping 1–2, 1–3, or 1–4 raw gold respectively with Fortune I, II, and III. Block. Gold Ore.

Look over the waste rock dumps around the old mines and prospects in the areas that interest you. Get to know the characteristics of the various ores. No two gold ores are the same, but ores in the same general areas may be similar. Look for iron stained quartz. The more oxidized or rust colored the better.
GOLD FLOTATION. The flotation process, which is today so extensively used for the concentration of base-metal sulphide ores and is finding increased use in many other fields. In 1932 flotation plants began to be installed for the treatment of gold and silver ores as a substitute for or in conjunction with cyanidation.
To retrieve fine gold you need a recovery tool with fine riffles or some type of fine matting. A normal gold pan will do if handled in a gentle manner, but a finishing pan with small riffles will make retrieving the gold much easier. To retrieve the really fine gold and increase retention rates, quite many prospectors use a Blue Bowl ...
