'Gewinnung' (extraction/acquisition) is a noun derived from the verb 'gewinnen' (to win/gain/obtain). The ending '-ung' turns the action of obtaining something into a process. So it is always about receiving, obtaining, or acquiring something.
Das Unternehmen will seinen Marktanteil gewinnen.
The company wants to gain market share.
The noun 'Gewinnung' is almost always used with a preposition that indicates what is obtained or what it is obtained from. The most common patterns are 'die Gewinnung von + dative' or 'die Gewinnung aus + dative'.
Die Gewinnung von sauberem Trinkwasser ist eine große Herausforderung.
The extraction of clean drinking water is a major challenge.
In the context of raw materials, 'Gewinnung' is often combined with materials that come from the earth or nature. Typical examples are 'die Gewinnung von Öl' (the extraction of oil), 'die Gewinnung von Kohle' (the mining/extraction of coal), 'die Gewinnung von Erzen' (the extraction of ores), or 'die Gewinnung von Salz' (the extraction of salt).
Die Gewinnung von Erdöl in der Tiefsee ist technisch sehr aufwendig.
The extraction of crude oil in the deep sea is technically very complex.
In the figurative meaning, 'Gewinnung' is used for intangible things. Common combinations are 'die Gewinnung von Informationen' (the acquisition of information), 'die Gewinnung von Energie' (the generation of energy), or 'die Gewinnung von neuen Mitgliedern' (the recruitment of new members).
Die Marketingabteilung ist für die Gewinnung von Neukunden zuständig.

'die Förderung' and 'die Gewinnung' can both describe extracting raw materials or substances from a source. 'die Förderung' is used especially for raw materials from the earth, for example oil, gas, or coal. 'die Gewinnung' is more general and refers to the process by which a substance is obtained or produced, for example salt, hydrogen, or energy. The words can be confused when talking about raw materials. In mining and oil contexts, 'Förderung' sounds very natural; in many chemical, technical, or general processes, 'Gewinnung' often fits better.
