"Oh?"
Dong's eyes slightly brightened, he picked up the teacup and asked nonchalantly: "How much usable Bismuth metal can be extracted from a ton of waste mine?"
"It mainly depends on the quality of the waste mine."
Lu Yuan said seriously: "Generally speaking, the extraction rate can reach one-tenth of normal production."
After Lu Yuan finished speaking, he clearly noticed that Dong's expression had changed a bit.
But he continued to shake his head incessantly.
"One-tenth is too low."
Lu Yuan got a bit "anxious," leaning closer to Dong, "eagerly" defending: "Dong, one-tenth is not low.
Don't forget, the waste mine is not worth much."
"Waste mine indeed isn't worth much."
Dong said slowly: "But have you considered?
Transportation, storage, and your extraction technology... these are all costs.
After calculating all miscellaneous costs, how much profit is left?"
"This...."
Lu Yuan was "at a loss for words."
