märkäprosessiksi

Märkäprosessi is a Finnish term that translates to "wet process" in English. It refers to a group of manufacturing or processing techniques that involve the use of liquids, most commonly water, as a primary medium or solvent. These processes are employed across a wide range of industries for various purposes, including cleaning, separation, extraction, chemical reactions, and material shaping.

In the pulp and paper industry, a prominent example of a wet process is the production of paper itself. Wood chips are broken down into pulp using water, and then the pulp slurry is spread and dried to form paper sheets. Similarly, in mining and metallurgy, wet processes are used for ore beneficiation, where valuable minerals are separated from waste rock using techniques like flotation and leaching, often involving water and chemical agents.

The textile industry utilizes wet processes for dyeing, washing, and finishing fabrics. These operations require the fabric to be saturated with dyes, chemicals, or water to achieve the desired color, texture, or performance characteristics. In the food industry, wet processing is common for activities like washing fruits and vegetables, extracting oils, and preparing ingredients for cooking or preservation. The pharmaceutical industry also employs wet processes for methods such as granulation, where powders are mixed with a liquid binder to form granules for tablet manufacturing, and for extraction of active compounds from plant matter. The core principle of a wet process is the interaction of materials with a liquid phase to facilitate a desired transformation or separation.
