Nowhere because no such salt or mineral block exists.
Quartz is the mineral that is the basic building block in many rocks.
The same as cows,Iron.
Colbalt chloride is not really the substance that most salt licks come in, rather it is a mix of sodium chloride with cobalt, iodine and other minerals put in a loose mineral or block for cows to consume ad libitum. Mineral blocks are very important to cows as this aids in health and fluid balance in the animal, healthy bones and teeth, healthy coat, cardiovascular system, enzyme activity, neuro activity, protein synthesis, etc.
None. No such salt block, medicated block nor loose mineral mix exists.
Cows are easily able to lick enough salt from a block to sustain them long term. Horses lack the ability to lick enough salt from a salt block, so most do better with loose salt. However, the ingredient (salt) in a horse salt vs. a cow salt is the same. Mineral blocks and loose mineral is different for cows and horses. Cows and horses have different mineral needs, but their requirement for salt is similar. Yes. Salt blocks are standard for both cows and horses: there really is no discretion as to whether a particular block is better for horses than cows or vice versa.
The smallest building block of a mineral is a atom.

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.
The same as cows,Iron.
A mineral block is a block that contains salts and other minerals for livestock to lick. Mineral blocks are provided as a supplement since a lot of the feed that livestock eat do not contain enough micro-minerals such as cobalt, iron, manganese, or iodine.
Diatomaceous earth is one such powder, which is essentially very fine sand. Lime is also a powdered mineral that has been successful at keeping pests from bothering cows.
Actually, its primarily one type of mineral that they need: Phosphorus. Phosphorus can be supplemented in a loose mineral mix from some sources including dicalcium phosphate, deflourinated phosphate, bone meal, soft phosphate, sodium phosphate, ammonium poliphosphate, orthophosphates, metaphosphates, pyrophosphates, and tripolyphosphate. Oilseed meals and animal and fish products contain large amounts of phosphorous. Grains, grain-by-products and high-protein supplements are fairly high in phosphorus thus rations that are high in these type of ingredients require little to no phosphorus supplementation.
This is a very important thing to do, yes, because the grass they eat doesn't have all the necessary minerals they need: they need to get it in either loose or block form. Ideally, summer time is best for blocks, and winter for loose, but you can feed loose and/or block all year round, your choice. Just note that mineral blocks have 95% salt in them, not nearly as much mineral as the loose form would have.
They can be if you give them a reason to, i.e. water, salt/mineral sources, etc.
trace mineral deficiencies can cause problems in herd.
