Can one be excommunicated for something that is not a mortal sin?
Excommunication is incurred for specific acts and they’re serious ones. Someone is excommunicated in order to make them realize what they’ve done and repent for it.
There’s a good explanation about excommunication at Catholic Exchange: catholicexchange.com/2008/01/25/81135/
Wikipedia lists various reasons for excommunication. (Wikipedia is not written by canon lawyers so keep that in mind.) The reasons they list include:
* an apostate from the faith, a heretic, or a schismatic; * a person who throws away the consecrated Eucharistic species or takes and retains them for a sacrilegious purpose; * a person who uses physical force against the Pope; * a priest who absolves an accomplice in a sin against the sixth commandment (the ban on adultery) except in danger of death; * a bishop who ordains someone a bishop without a pontifical mandate, and the person who receives the ordination from him; * a confessor who directly violates the sacramental seal of confession; * a person who procures a completed abortion; and * accomplices who are not named in a law prescribing latae sententiae excommunication but without whose assistance the violation of the law would not have been committed.
Various other persons incur excommunication latae sententiae by papal decree, including:
* a person who violates the secrecy of a papal election, or who interferes with it by means such as simony; * a woman who is ordained as a priest or a bishop who ordains a woman as a priest.
Some instances in which one incurs interdict latae sententiae include the following:
* using physical force against a bishop; * attempting to preside at Eucharist, or giving sacramental absolution, when not a priest; * falsely denouncing a confessor for soliciting a penitent to sin against the sixth commandment; and * a perpetually professed religious who attempts marriage.

Oh thanks but I did not mean can someone be excommunicated for something that is not grave matter, I was more thinking of grave matter but without full knowledge.
Excommunication is for the specified mortal sins I listed. If someone does not know a sin is grave matter then they have not committed a mortal sin.
