I’m asking this because, I want to know where to dig in order to find precious metals and stones.
Q-1: Do they regenerate?
Q-2: Where to look for precious materials?
Because, I want to find cool, diamond, gold etc... and to know whether they regenerate or not so that I can be near to them. Because now, it’s hard for me to find precious metals and diamond in Minecraft. I mean, when I find gold on a rock somewhere and by mistake I lost them, then I must find another place to look for it.
(preface - y-leves are how many blocks above the void you are - and you can find a value for it in your F3 menu (the one you get by pressing F3))
Gold is found between y levels 2 to 29 (approximately).
Diamonds are found below y level 16 (and most commonly between layers 5-12).
No ore, or block in the game will "regenerate" (although trees and crops "grow") itself over time, so once you've mined an area out it will stay that way.
When it comes to mining diamonds, only 1 vein will spawn per chunk (unless it's eaten by a pre-world generation structure, like a dungeon or mineshaft).
The "Mountains" Biome has emerald ore and no other place does (besides trading with villagers). In "Badlands" and "Eroded Badlands" There is more Gold ore and at a higher Y level than 32. you can check if you are in these locations by hitting f3 and looking at the name beside "biome:".
Make a pickaxe and dig down. Be careful of lava, don't dig straight down. Generally digging a staircase is safer as you will not fall into a lava lake and can run backwards if you dig into lava.
From the wiki on mining about choosing which layer to mine:
- Levels <5: bedrock
- Levels <30 lava, although Lava has been found elsewhere.
- Levels <14-5 diamond and redstone
- Levels <30 gold and lapis lazuli
- Levels <60 iron
- Levels <70 coal
- Gravel generates between layers 1 and 111.
- Note: If you are in a mesa biome, you would want to look for gold near the surface.
Due to being the safest layers to mine where all ores exist in reasonable quantities (especially diamond), Y-coordinates 10 to 15 are usually considered the best area in which to start mining. The single best layer for mining is highly debated and is not agreed on. Using the debug screen (F3) is the easiest way to find your altitude.
Use the debug screen accessed by pressing F3 to determine your current Y level when you are mining.
Here is the top left corner with the debug screen showing Y level of 73:
Well it all depends on which type you are on. iIf you are in a part where you can't check your Y level, then check near lava. I found it there sometimes.
