Valuable metals are removed from ores during the process of Metallurgy, which typically involves several steps, including extraction, refining, and purification. This process often includes methods such as pyrometallurgy, hydrometallurgy, or electrometallurgy, depending on the type of metal and ore. These techniques help separate the metal from the ore and eliminate impurities, allowing for the recovery of valuable metals like gold, silver, and copper.
Because many valuable metals like platinum are dense so most of them have sunk into the molten center of the earth at some point during history leaving relatively small amounts in the crust. This cannot happen in an asteroid as there is nowhere for valuable metals to sink so they remain easily retrievable. That's why so many metals that are rare on earth are plentiful in asteroids, thus making them valuable.

Decomposers play a role in bioleaching, a process used in mining to extract metals from ores. They break down organic matter or sulfide minerals in the ore, releasing valuable metals in the process. This can help make certain metals more accessible for extraction.
Metals such as nickel, copper, and cobalt are commonly extracted using phytomining. This process involves growing hyperaccumulating plants that can absorb high levels of metals from the soil through their roots. Once the plants are harvested, the metal-rich biomass is collected and processed to extract the valuable metals.
Anode sludge is a byproduct generated during the electrolysis process in metal refining, particularly in the production of copper and other non-ferrous metals. It consists of impurities, such as oxides, sulfides, and other metals that are not deposited on the cathode during electrolysis. This sludge can accumulate at the bottom of the electrolytic cell and may require periodic removal and treatment to recover valuable metals or to manage waste. Proper handling of anode sludge is essential to minimize environmental impact and enhance resource recovery.

An ore is a mineral or rock from which metals and nonmetals can be extracted and used in significant quantities. Ores are typically processed to extract valuable elements for various industrial applications.

One can effectively separate precious metals from catalytic converters by using a process called chemical leaching, which involves dissolving the metals in a strong acid solution. This method allows for the extraction of valuable metals such as platinum, palladium, and rhodium from the catalytic converter material.
