Iron ore is a mineral block found underground. It is a source of raw iron, which can be smelted into iron ingots. Deepslate iron ore is a variant of iron ore that can generate in deepslate and tuff blobs. Iron ore itself can be obtained by mining it with a stone pickaxe or higher enchanted with Silk Touch. When mined without Silk Touch, iron ore drops raw …

The metallic content of agglomerates is influenced by the gold content, gold recovery, and carbon/ore ratio. For example, it has been determined that ores with 1 g/t of gold will form agglomerates with 1,050 – 1,550 g/t of gold. The recovery can be improved by adding surfactants. This action is similar to the conventional flotation.
