The first place they took us was the mine. It's an open pit copper mine that has been operating for nearly 50 years and has another estimated 40 years of life left. They blast out layers of ore containing their two primary products, copper and molybdenum (there are other trace elements such as silver and gold but they are in much smaller amounts). The rocks are loaded onto giant earth moving trucks, dumped through crushers and either carried away by conveyer (gravity pulls the crushed rock along the down-hill conveyor - in fact they generate electricity from the turning conveyor) or by train car depending on whether it's low-grade or high-grade ore (they use very different processes to extract the metals depending on the grade of the ore).
Our guide was Teresa, the director of public relations, and she was so kind and informative.
What you see below is the crusher into which the trucks load the low-grade ore before it is taken away by the conveyor.
These trucks are HUGE. Each one costs about $4M (each tire costs $35K and is used for about a year). You can see that the whole family is standing in front of the bottom half of one tire.
In the low-grade ore process (which they've only used for the last 10 years or so) they are able to recover some of the highest purity copper (99.9996% pure) in the world they leach copper out of the rock by sprinkling acidic water over the stone for years and alternately letting a special stone-eating bacteria degrade the ore. The acidic water with the copper in is concentrated through chemical separation processes and then put in large tanks where electrically charged meter-square stainless steel plates are dipped for 5 days. When they pull the plates out of the electrolysis a half-centimeter copper plate has formed on each side. They clean and flex the stainless steel plates to remove the copper plates. This process alone generates 100 tons of copper per day.
The high-grade ore is crushed and then ground until it's a powder (the final set of grinders are giant tumblers filled with the soft-ball-sized steel balls that you see below) mixed with water that flows with the consistency of a thin shake. Then it is separated in a bubbler where the minerals rise with the foam. The molybdenum is removed and the remainder is dried in a kiln to a powder. This copper rich powder is loaded on train cars and sent to a smelter in Ilo (down on the coast).
After the mine took us to a cafeteria for lunch and we saw the mailboxes the kids used to run to to get the mail.
We also so the old American school where the four oldest went when we lived there.
We went to what had formally been the Mormon church built by the efforts and funds of our family and many others back in the late 1950s. It's now a company training center.
We found the house we had lived in, and though we weren't able to go inside (the current resident was on vacation) we did take pictures in front of it, listen to the older ones reminisce about their memories, and went to the ravine behind it where dad had built them a playhouse (now gone).
I was born two months before they finished the hospital so mom went to a small clinic down near the entrance at a place called Incapuquio. The building is now gone and there's a golf course there now. My sister Lucy was born a year-and-a-half later in the Toquepala hospital. We stopped by and took pictures of the outside but didn't see the entrance and it was late in the day so we loaded up the van again to leave. At that point I noticed a window that said something about hospital records so Lucy and I went over to ask about whether they had our records. They said that records that old were archived and would take some research, but the man in the office insisted that we visit the hospital itself.
He took us up to the top floor (there are three) and got a nurse to find the key to the delivery room. When he opened that door we realized that THIS was the very room in which our mother had gone through delivery and where Lucy had first seen the light of day. We went back to the van and called everyone to come join us. I took a picture of dad and Lucy in the delivery room and then suddenly I felt mom with us again. The tears started to flow and we found ourselves feeling that this was a sacred moment.
This trip to Toquepala was the primary purpose of our trip to Peru and it didn't disappoint. Prior to this the fact that I was born in Peru was purely academic. Now I feel connected to the place. I feel Peruvian.
Amazing photos- thanks for posting! Can't wait to hear more of the details!!
ReplyDeleteThanks for sharing, your mail box was really close to ours, we might even have inherited yours
ReplyDeleteThanks for sharing your adventure. There are a lot of us that got our start in Toquepala. I will share this link with those in my "Toquepala Group".
ReplyDeleteBy the way, are you aware there is a Toquepala reunion next month in Tucson? It originated in the 60s in Silver City by Nora Jarvis Gilpin, and several other former Toquepalenos. If you'd like more info you can visit www.toquepala.com, or contact the SPCC reunion planning committee at toquepala@gmail.com
i have a photos of 2 small blonde girls and their mom in 1958 that my folks always referred to as "Mormon" when we looked at the slides.

That was a great trip with the excellent photos. I always wondered how hard it was to get into Toquepala.It sounds like it was pretty easy.So its not necessary to gain permission before you arrive? We lived across the street down one house next to the Josephsons and the Delius.Directly across the street from the Crockers.
ReplyDeletethanks again for sharing. REunion is next month in CAtalina State Park.

I don't know if you will read this. I was a missionary in Tacna and on May 9, 1975 I visited Toquepala with the District President (Zeballos) and we stayed with the George Whitiker family (from Bountiful) and the Ray Avery family. It was a highlight of my mission. We saw the chapel, but I was happy to see your picture. Thank you
