1) The Tur brings the Rashba who holds that although basar b’chalav has a din of issur machmas atzmo and is a nevaila and 60 is needed against the entire ta’aruvos to m’vatel it, still if we separate the meat and milk both may return to muter.

The Shach argues with the Rashba and holds that basar b’chalav is an issur machmas atzmo. Even if the milk is separated from the meat it is still ossur.

2) In simon 92, we see that a piece of meat that is out of the rotev that absorbs a drop of milk becomes ossur by bb"ch if the meat does not have 60 against the milk. If it is assur after being separated it will osser another piece touching it.

3) Issur machmat atzmo is a food that is inherently not kosher such as tameh cheese or neveilah meat. An issur balua is a kosher food that has absorbed a non-kosher food -- such as a piece of meat that absorbs blood. The halachik difference is if the blios will go into another piece without rotav.

4) According to the Maharai so long as the milk and meat are combined it is called an issur machmas atzmo, but if it is separated it is mutar. According to the Shach the din of basar b'chalav can not be removed even if the meat is by itself. Therefore, it always has the din of an issur machmas atzmo.

5) Just as if a garment has shatnez, if a part that does not have linen in it is cut off it can be worn, basar b'chalav as well is mutar if the milk is totally separated from the meat.

6) Although we are not normally proficient to diffreniciate between kachush and shamian, by issur balua we are proficient.

7) Milk is kachush according to the Shach.

8) According to the Taz no, according to the Shach if the meat is shamian it will osser kulo and if it is kachush it will osser a klipa.
