"When we've removed all the valuable minerals and the rest of the material returns from the plant - 100% of the material is sent there, but only 5% of it is valuable titanium ore - the remaining 95% is returned here, spread out, and the land will be reclaimed," Mr Holik said.
Its director of mining told Sky News that it would take at least 200 years - probably more - to extract all the titanium ore from across Ukraine.
Mr Holik said he would welcome American or any other foreign investment into Ukraine to help the country improve its ability to extract its mineral reserves.
Ukraine's president also wants to use his deal with Mr Trump - which could be signed on Friday when the two leaders are due to meet in the White House - to secure American military support against Russia in the event of a ceasefire deal.
"Right now, our local investors simply lack the financial capacity to fund large-scale factories, deep-processing facilities, and advanced technologies... "If a major international investor steps in - one with a long-term vision, not just for five or 10 years, but for 40 to 50 years - it would be a game-changer.".
