What is an "Extracted Preview"?
There is a plug-in that will enable you to recover files from the icons in Lightroom. I had an unfortunate crash and wanted to keep some of the files; and Extract Preview enables that. See this from Adobe:
It works really pretty good as long as you have a 1:1 preview in lightroom; otherwise, the image created is too small to work with. As stated above, it does't always work on the previews.
Hope you or someone can shed some light on this issue.

There are (up to) 7 different previews per photo:
* smaller still
* tiny thumb.
'Extract Previews' should extract the largest, whether 1:1 or otherwise.
What it won't do is assign a proper icc profile (or metadata) to the extracted image, so color will be off, and of course it will be devoid of metadata.
I fully understand that the icc profiles aren't generated; however that is not my question or problem. For example, I extracted a preview and it created a .jpg image; however, when I import that image into LR, it creates a second image on the hard drive. However, if I rename the image before importing it, it imports as expected...strange. Another strange instance concerns two previews that are 1:1 that will not extract. LR says that the task is completed, but when I go to the HD they are simply not there. I have experienced this on several images, but two of them I really would like to save, but cannot..
Thanks for trying to help me solve this puzzling thing.

Dunno.. - sorry.
previews that are 1:1 that will not extract.
Either your previews are afoul, or Adobe's script is not robust, or your assessment that 1:1 previews were available is erroneous, or something else I can't think of..
* Try Jeffrey Friedl's Preview Extractor (it uses an algorithm he reverse engineered, and may actually cover cases the Adobe programmer missed).
* Try my PreviewExporter (e.g. preview recovery feature) - it uses an algorithm I came up with through reverse engineering and may cover cases Adobe and/or Jeffrey Friedl missed.
