Zero. There are no salt blocks available on the market that have ephedrine in them.
Nowhere because no such salt or mineral block exists.
None. No such salt block, medicated block nor loose mineral mix exists.
There really is no such salt block or mineral mix. You can check with your veterinarian or those companies that make livestock salt blocks but it's highly likely you will not find such an ingredient in salt licks for cattle.
Quartz is the mineral that is the basic building block in many rocks.
That depends on how much mineral you have.

None. No such salt block or loose mineral mix exists.
None. No such salt block, medicated block nor loose mineral mix exists.
There are no salt or mineral nor medicated mineral blocks that contain any form of ephedrine in them. Sick animals are treated by antibiotics via injection, not by just giving them a "medicated" salt block.
You cannot extract ephedrine or pseudoephedrine from a mineral block. Anyone who tells you that they have done it is either mistaken or a liar. The claim that ephedrine can be extracted from a livestock mineral block has been proven as false and erroneous by Drug Enforcement Administration (DEA) scientists upon attempting to extract ephedrine from mineral blocks through various methods that have been "tried and tested" by various people. The only reason that these people would be wanting to attempt to extract such substance from mineral blocks would only be for the purpose of making an illegal narcotic drug called Crystal Meth. Apart from the evidence gathered by the DEA, scientists from an anonymous major feed-producing company have also "concluded that [mineral salt blocks or licks] contain no ephedrine or pseudoephedrine." However, the DEA article below does mention that salt (NOT ephedrine nor "psuedoephedrine") from such mineral blocks can be extracted for the production of Crystal Meth.(Note that producing such a highly illegal substance can and will land you in jail. If you aren't in jail yet for taking or making such narcotics, it's only a matter of time before you are.)Please see the related links below.

The smallest building block of a mineral is a atom.

The brain does not produce ephedrine, as it is not a chemical the body produces.
None because no such block exists.

No. All mineral blocks have enough salt in them to sustain cattle alone without having to have an additional salt block set out. Because mineral blocks are called "trace mineral" blocks, this means that 95 to 98% of the block is comprised of salt, while the other 5 to 2%, respectively, is composed of mineral.
