You lied in your recent UK application when you answered the question about previous visa refusals from any country negatively. The question says “Have you ever been refused...” - it’s quite clear, it’s not time-bound such that an old refusal no longer needs disclosure after the passage of time, and it doesn’t give any extenuating circumstances under which answering ‘No’ when the truthful answer is ‘Yes’ is allowed. The ‘missing’ passport makes absolutely no difference to the requirement to answer all questions truthfully.
The implications are that you have dug yourself a hole without an exit. You must disclose previous refusals or risk being found out eg through biometric data sharing with the US. If you disclose or you don’t but the UK finds out, you’ll automatically be refused under Immigration Rule 320 (7A) https://www.gov.uk/guidance/immigration-rules/immigration-rules-part-9-grounds-for-refusal
Your only hope might be to consult an Immigration lawyer, however this is likely to be very expensive (if you can find one willing to help) and very possibly fruitless. After all, what explanation do you have for knowingly lying? https://www.gov.uk/find-an-immigration-adviser

If you have been refused a visa in the past then it's you who has been refused, not your passport. It's irrelevant whether you have subsequently changed passport, whatever the reason.
If you have failed to disclose that refusal in a subsequent application you now have a problem. If the country to which you are now applying knows about that refusal but you fail to disclose it they will deny you entry and possibly impose a long ban for deception.
If you do now disclose the previous refusal, the country to which you're applying will want to know why you didn't disclose it before. If you don't have an excellent explanation they will deny you a visa and possibly apply a long ban for deception.
From the tags and your comments it appears that you are applying to the UK, having been previously refused by the US. Those countries share a lot of immigration information. You should assume both countries know everything about your visa history.
Your history of visa refusals coupled with a failure to disclose previous refusals makes your situation complex. You would do well to consider employing a UK lawyer with immigration experience if you seriously want to visit the UK.
