Crossword puzzles can lead players into fascinating corners of language, history, and even industry-specific terminology. One such intriguing entry is the phrase ‘ore washing trough,’ often appearing as a crossword clue that leaves solvers scratching their heads. While it may sound technical or outdated, this term has historical significance and a clear purpose in the context of mining and metallurgy. Understanding it not only helps with puzzle-solving but also offers insight into a part of industrial history that laid the groundwork for modern extraction methods.
What Is an Ore Washing Trough?
Understanding the Basics
An ore washing trough is a simple but vital piece of equipment historically used in mining operations. It’s essentially a long, narrow basin or channel through which crushed ore and water are passed. The goal is to separate valuable minerals from debris, clay, or lighter rocks through a process called gravity separation. The heavier ptopics, often containing metal ores, sink to the bottom, while the lighter waste materials are carried away by water.
Historical Usage
Before the advent of modern mechanized mining equipment, ore washing troughs were commonplace. They were usually made of wood and used in gold, tin, and coal mining, especially during the 18th and 19th centuries. Miners relied on this method in combination with sluices, pans, and other rudimentary devices to extract valuable content from raw geological material. The simplicity of the trough made it an efficient tool in small-scale operations or during the early phases of industrial mining.

Common Clue Formulations
When ‘ore washing trough’ appears in a crossword, it’s usually presented with a hint suggesting a historical or mining-related word. The most common solution associated with this clue is launder. In this context, launder does not refer to washing clothes but rather to the channel or trough used in the ore-washing process.
- Clue: Ore washing trough (7 letters)
- Answer: Launder
This particular crossword clue is a good example of how a word with one commonly known meaning can have an entirely different definition in another context. Solvers must often think beyond their everyday understanding of a word to find the right answer.
Strategies for Solving Similar Clues
For crossword enthusiasts, clues like ‘ore washing trough’ require some lateral thinking. Here are a few tips:
- Think historically many industrial clues refer to outdated equipment or processes.
- Look at the word length. Seven-letter clues relating to troughs often point to launder.
- Consider multiple meanings. Words can have both domestic and technical definitions.
The Etymology of ‘Launder’
From Water to Metal
The word launder is derived from the Latin word lavare, meaning to wash. While we typically associate laundering with cleaning clothes, in the mining context, it refers to washing or rinsing ore. The ore washing trough, or launder, earned its name due to its function of ‘laundering’ mineral-rich rock.
Language Evolution in Technical Fields
This dual usage is an excellent example of how language evolves based on usage across different sectors. In industrial and geological applications, a term like launder holds a specific and technical meaning that diverges significantly from everyday use. Such variations make crossword puzzles particularly challenging and interesting for word lovers.
The Role of Ore Washing Troughs in Mining
Separating Ore from Waste
At its core, ore washing is a beneficiation process. It helps increase the quality of ore by removing impurities. Troughs are used to pass water and finely crushed ore together. Due to gravity, heavier and more valuable ptopics like gold or iron will settle at the bottom, while lighter, worthless ptopics float away.
Advantages of Using Troughs
- Low-cost method for small operations
- Simple design with minimal maintenance
- Effective in gravity-based separation
Modern Replacements
Today, ore washing troughs have mostly been replaced by advanced equipment like spiral concentrators, flotation cells, and jigging machines. However, in some artisanal mining regions, the original launder design is still used due to its affordability and effectiveness.

Why Niche Terms Appear in Puzzles
Crossword constructors often include obscure or technical words to add complexity and variety to their puzzles. This keeps solvers engaged and challenged. Words like launder, when used to describe an ore washing trough, serve as perfect crossword material familiar yet misleading when taken out of context.
Learning Through Crosswords
Solving clues that reference specific professions or historical tools enhances a player’s vocabulary and general knowledge. Many crossword enthusiasts find that they learn more about engineering, science, or history simply through regular puzzling. Understanding what a launder is in mining, for example, may seem trivial, but it adds another layer of knowledge to the solver’s toolbox.
