Chemical processes and chemical reactions difference
According to IUPAC:

Chemical reaction
A process that results in the interconversion of chemical species.
Chemical reactions may be elementary reactions or stepwise reactions
(It should be noted that this definition includes experimentally
observable interconversions of conformers.) Detectable chemical
reactions normally involve sets of molecular entities as indicated by
this definition, but it is often conceptually convenient to use the
term also for changes involving single molecular entities (i.e.
'microscopic chemical events').

A chemical reaction is a kind of process in which interconversion of chemical species takes place. Because of this, we can say that a chemical reaction is a chemical process.
Chemical process can be a broad term, which describe any process that is commonly studied by chemists because they are closely related to chemical reactions. It is somewhat diffuse, as boundaries of the field of chemistry.
Industries use a variety of procedures to obtain substances. Chemical processes/reactions take place. If your interest is realising what is done in industries, do not get stuck in these subtleties. Most of the times they are not intentionally distinguished, and their usage is customary in the field.
