In order to use the Extractinator, it first needs to be placed in the world. Afterwards, suitable blocks need to be consumed (with the ⚒ Use / Attack key) directly on the Extractinator within its 3×3 frame.
Feeding blocks to the Extractinator is the only way to obtain Amber Mosquitoes, and, along with opening crates, the only reliable way to obtain a world's alternative Pre-Hardmode ores. This is a great way to obtain ore and coins in the early game.
The world-generated ores appear with equal chances as their alternatives, e.g., the Extractinator produces an equal chance of Gold Ore and Platinum Ore, regardless of which is found underground in that world.
Unlike crates, the Extractinator will not provide Hardmode ores even if the world is in Hardmode. It will not produce high-tier pre-Hardmode ores such as Demonite, either.
A full stack of 999 Silt or Slush Blocks yields a fair collection of loot. The table below breaks down, prorates, and summarizes the sale prices.
Most of the gems are much more valuable when crafted into Stained Glass: Each gem except Diamond makes 1 worth of Stained Glass.
The gems can also be crafted into Gemcorns, to grow more gems directly.
Diamonds cannot be turned into Stained Glass, or anything else with a higher sale price than the gems.
Notice how much of the total average payoff comes from the small chance of obtaining Platinum Coins. The total yields are normally 8 or 9 or so lower, but with a 6%-7% chance per 1000 blocks of a platinum jackpot.

Due to the dangers of the Underground desert, the lower chances of getting ores/coins/gems (but amber) and how common Silt is in other biomes, Desert fossil is a less viable option for getting ores/coins/gems.
When moused over on the minimap, its name appears as "Silt Extractinator".
