The phrase "sort out/separate the wheat from the chaff" means to distinguish between what is valuable or useful and what is not. It is usually used when you want to find the best or most important things among a large group of things that are not very good or useful. For example, if you were trying to hire someone for a job, you would need to sort out the best candidates from those who are not as qualified. The phrase comes from the process of separating the edible part of a plant (the wheat grain) from the inedible part (the chaff) during harvest.
