Pre-Build
Before building a slime farm, first decide whether to build it in a slime chunk or swamp biome. Every chunk that is generated in a world has a 10% chance of being a slime chunk. Within slime chunks, slimes can spawn up to Y=39 inclusive. This method requires an underground room to be dug out before the farm is constructed. Slime spawning in swamps can occur between Y=51 and Y=69 inclusive. This method has the advantage of not requiring a dug-out room prior to building the farm, and the size of the farm is not limited, unlike the slime-chunk method.
Spawning
The first step in constructing either farm is the spawning place. In most farm designs, spawning platforms are created which spawn slimes that are then moved to a killing trap, usually a drowning trap to split larger slimes down and dispatch the smallest size. Spawning pads are usually constructed with a 2ℂ₂-block gap using slabs, to allow all types of slimes to spawn. It is important to light the spawn platforms up, otherwise other hostile mobs can spawn too. It is also recommended to light the area in a 128-block radius around the farm, so as to keep the hostile mob cap See the natural spawning of players and mobs. For mob spawners, see Monster Spawner. For the player, see The Player. This article needs updating. Description: Rabbits now spawn in deserts with new

and above.
Separation and killing trap
The final step in building a slime farm is the separation and killing trap. To separate the different sizes down to the smallest, a drowning trap is usually used. The largest type of slime is split to the medium size, and medium to small. The slimes are then taken off to another trap to be killed, usually another drowning trap. For greater efficiency, the separation trap could be used as a killing trap as well, although this can be difficult in slime farm traps if the spawning room is too small.
Alternatively, a water stream carrying the slimes flowing into a cactus trap can be used. Hoppers around the base of the cacti then collect the drops. This has the advantage of killing all sizes of slimes without the need for separation. Be that as it may, the cacti have a small chance of destroying the slimeballs that are dropped.

Jioge`s 1.8 Slime Grinder Tutorial
Many slime farms, especially those involving iron golems and the mechanic of slimes sinking into a water pit, were broken in 1.8 releaseAnnounce of Minecraft. Jioge has the solution with this simple trap. Slimes are now able to swim upward and on a horizontal axis, so it is important to take note of how Jioge places the water in the drowning trap.
ilmango`s 1.10+ Slime Farm (18,200 slimeballs/h)
This slime farm`s design is quite different from most of the others. Indeed, it uses fewer spawning pads, which, due to the way the slime spawning algorithm works, increases the spawning rates (see video for more details). The slimes are then lured off of the platforms using iron golems and killed by magma blocks.
