python fuzzywuzzy's process.extract(): how does it work?
process.extract actually uses WRatio () by default, which is a weighted combination of the four fuzz ratios. This is actually a cool functionality that empirically works pretty well across fuzzy matching scenarios. Still, you can manually specify the string comparison function via the scorer argument to extract

Extracting Gold From Rock Gold by Gold Separator Process Line
Extracting Gold from Rock Gold by Gold Separator Process line The content of gold in the ore is extremely low. In order to extract the gold, the ore needs to be crushed and ground and the beneficiation method is used to pre-enrich or separate the gold from the ore. The most widely used in gold beneficiation is gravity separation and flotation.
