Google is your friend, online there are lot of articles, this one is from nature protocols (http://www.nature.com/nprot/journal/v2/n2/full/nprot.2006.478.html)
Check another one from experimental biosciences. (http://www.ruf.rice.edu/~bioslabs/studies/mitochondria/mitoprep.html)
If you can afford kit for isolation of mitochondria, here it is.
Mitochondria Isolation Kit for Tissue (ab110168) (http://www.abcam.com/mitochondria-isolation-kit-for-tissue-ab110168.html)
Well, we have used a commercial kit available from Biovision Labs USA. The product is economical and has a user-friendly protocol. We have a couple of publications in which this particular kit was used. Please refer to the kit Technical Data Sheet and follow the instructions for tissue samples.

The above answers are very adequate. We isolate mitochondria on a routine basis from many tissues including liver. But the key questions are: what do you want the mitochondria for and how pure do you need them.
thanks for your contribution , actually virgilio sir, i want to isolate mitochondria by normal manual method , because we cant afford kit for that and check enzyme assay of electron transport cycle .
This paper provides you with the protocol for the isolation method for several tissues, including the liver and it was the basis of the protocol in our lab.
There are thousands of papers on mitochondrial isolation from liver of many mammals. Actually it does not matter whether it is albino rats of mice or rabbits etc.
