Gold has a variety of uses, and while you're mining Gold veins you even have a chance to get rare gem drops, too. Various gems can drop while mining Gold veins, depending on mining skill and mining luck, including Rubies, Sapphires, Topaz, and more.; Gold can be smelted into Gold Ingots, which are used to craft a huge range of items, including the more advanced …
Ores can be smelted faster using a blast furnace.. It is not efficient to mine with Silk Touch and then smelt an ore block that normally drops multiple pieces of its resource, because smelting these ores yields less experience and only 1 piece of the resource. Nether gold ore is the only exception, as each ore block drops an average of 8.8 gold nuggets even when …

Before gravity separation, the manganese ore is first crushed (6-0mm or 10-0mm) and then classified. The coarse-grained manganese ore particles enter the jig for sorting; the fine-grained ore particles are sent to the shaker for sorting. Commonly used equipment includes gravity separators, spiral separators, etc.
