Selective Leaching for Uranium and Gold from their …
The extraction of uranium from Randfontein ore has been studied at a temperature of 110°C using sodium carbonate and sodium bicarbonate. The leach was followed by cyanidation of the ore to extract the gold. The results show that 90% of the uranium and 98% of the gold can be extracted by this technique but the . Pyrometallurgy

Titanium Ore | Chaos Awakens Wiki | Fandom
Titanium Ore is a rare ore that generates underground, and is a reliable source of Titanium. Titanium ore can generate in the Overworld and in the form of blobs. Titanium ore attempts to generate 3 times per chunk in blobs of 1-4 ore, in layers 0 to 13 in all biomes. If multiple blobs spawn directly adjacent, it is possible to have a "singular blob" with more than 4 titanium ore. …

This document summarizes the process of bioleaching, which uses microorganisms to extract metals like copper, gold, iron, and uranium from ores. It discusses how different bacteria are used to oxidize the metal sulfides in ores, making the metals soluble and able to be extracted. The main methods used are heap leaching and in-situ leaching.
