That's tough, nobium and tantalum have such special characteristics that it isn't easy to find a replacement. Coltan is the colloquial African name for columbite - tantalite, a dull black, metallic ore from which the elements niobium (formerly "columbium") and tantalum are extracted.

What is a good replacement for lubricant?
A good replacement for lubricant can be natural oils like coconut oil or olive oil. These oils are safe, affordable, and can provide a similar level of lubrication during sexual activities. However, it is important to avoid using oil-based lubricants with latex condoms as they can degrade the material.

How is Coltan concentrated?
Coltan is typically concentrated through a process called gravity separation, where the ore is crushed and then subjected to gravity-based methods to separate the heavier coltan minerals from the lighter gangue minerals. Another common method is magnetic separation, where coltan-bearing minerals are separated based on their magnetic properties. These processes help to increase the concentration of coltan in the ore for further processing.

The extracted coltan is then further processed to separate the tantalum and niobium minerals from other components in the ore.
