“mind” vs. “mined”
Use "mind" for the noun meaning intellect or the verb meaning to pay attention to or object to something; use "mined" only for the completed act of extracting material or information from a larger source.
mind
"Mind" functions as a noun referring to a person's intellect, consciousness, or memory ("a sharp mind," "keep it in mind") and as a verb meaning to pay attention to, to object to, or to take care of something ("mind the gap"; "would you mind helping?"; "mind the children"). It comes from Old English "gemynd" (memory, thought), related to Latin "mens" (mind) and the English word "mental," part of a very old and widespread Indo-European word family concerned with thought and memory.
mined
"Mined" is the past tense of the verb "mine," meaning to extract minerals or resources from the ground ("the company mined coal for decades"), and by extension, in a more modern figurative sense, to extract useful information from a large source ("researchers mined the dataset for patterns"). It comes from Old French "miner" (to mine, to undermine), itself likely from a Celtic root referring to ore, entering English in the medieval period alongside the growth of organized mineral extraction.
The real distinction
In most accents "mind" and "mined" come out sounding identical, the vowel and final consonant lining up exactly, yet their meanings point in completely unrelated directions: one concerns thought, attention, and consciousness, the other concerns extracting material from the ground. The test is straightforward once you notice grammatical role: "mind" functions as either a noun (something you have, keep, or lose) or a present-tense verb (something you do right now, as in "I don't mind"), while "mined" always signals a completed act of extraction, sitting squarely in the past tense. If the sentence describes a person's thoughts, attention, or objection, or uses the word as a command ("mind your step"), you want "mind." If the sentence describes something being dug up, extracted, or figuratively pulled out of a large body of data, in the past tense, you want "mined." A useful confirmation: "mined" will almost always have a direct object naming the substance or information extracted ("mined the coal," "mined the archives"), a structure "mind" as a verb doesn't share in the same way, since "mind" as a verb more often takes a full clause or gerund as its object ("mind the noise," "don't mind waiting"). The figurative sense of 'mined,' describing data or information extracted from a large source, has grown substantially alongside the rise of data science and analytics, giving 'mined' a second modern life well beyond its original meaning limited to coal, ore, and other physical materials. Psychology and neuroscience writing relies heavily on 'mind' to discuss cognition, consciousness, and mental health, an entirely different specialized vocabulary from mining and data-science writing that relies on 'mined,' whether describing coal extracted from a mountain or patterns extracted from a dataset, two very different kinds of extraction sharing only the same past-tense verb form.

Memory trick
Picture "mind" as the seat of thought — it shares its opening letters with "mental," a quick etymological anchor for the meaning. For "mined," remember it's simply "mine" plus the regular "-ed" past-tense ending, so if the sentence describes something already dug up or extracted, the spelling follows the ordinary rule for past-tense verbs.
